10 Differences between chemiosmosis in Cellular Respiration and Photosynthesis

Chemiosmosis in Cellular Respiration vs chemiosmosis in Photosynthesis
Chemiosmotic Hypothesis was proposed by Peter Mitchell 1961. He was awarded the Nobel Prize for Chemistry in 1978. This process is occurring during cellular respiration and photosynthesis.
Chemiosmotic Theory states that Electron transport and ATP synthesis are coupled by a proton gradient across the inner mitochondrial membrane.
Peter Mitchell proposed this theory to explain ATP synthesis during cellular respiration

5 Differences between Proteinogenic Amino Acid and Non-proteinogenic amino acids

Proteinogenic vs Non-proteinogenic amino acids
Proteins are nitrogen containing bio molecules made up of amino acids joined by peptide bond.
An amino acids consists of a central α carbon atom joined by 4 groups namely Hydrogen (H), amino group (–NH2), carboxyl group (-COOH) and side group (R-group).
Proteinogenic amino acids are “protein forming amino acids where as non-proteinogenic amino acids not naturally incorporated into proteins
 Proteinogenic Amino Acid vs Non-proteinogenic amino acids
Proteinogenic amino acids
Non-proteinogenic aminoacids
Proteinogenic amino acids are those which are naturally encoded in the genetic code of any organism
Non-coded or non-proteinogenic amino acids are those not naturally encoded or found in the genetic code of any organism.
Natural amino acids incorporated into proteins during translation
Amino acids not incorporated into proteins during translation
Protein forming amino acids or amino acids that are natural constituents of proteins
Not Protein forming amino acids or amino acids that are not naturally incorporated into proteins
Coded amino acids or proteinogenic amino acids are those which are naturally encoded in the genetic code of any organism
Non-coded or non-proteinogenic amino acids are those not naturally encoded or found in the genetic code of any organism.
Examples: In Eukaryotes all 21 amino
acids including selenocysteine are  proteinogenic. (Glycine, alanine, valine etc)
Ornithine, citruline, Gamma-Aminobutyric Acid (GABA) etc
Forms all proteins that carry out different activities of the cell like enzymes, hormones like insulin.
They are often intermediates in biosynthesis with specific physiological functions.
For example GABA is a neurotransmitter that blocks impulses between nerve cells in the brain.

10 Difference between Hexokinase and Glucokinase

Both Hexokinase and Glucokinase are enzymes catalyzing the phophorylation of Glucose to Glucose-6-phosphate using ATP. During the reaction, one ATP molecule is cleaved to ADP and the phosphate thus released is added to glucose. Hexokinase and Glucokinae are isoenzymes with same catalytic activity but have different physical properties and site of action. Glucokinase is also called as human hexokinase IV, hexokinase D etc
10 Difference Hexokinase vs Glucokinase
Hexokinase
Glucokinase (Hexokinase D)
Present in all tissues except the liver and the Beta cells of pancreas
Present in liver and Beta cells of pancreas
Acts upon many hexoses such as fructose, galactose including glucose
The only substrate is D-glucose
Hexokinase is one of the regulatory enzymes of glycolysis
Glucokinase plays a central role as a glucose sensor in the regulation of glucose homeostasis.
Hexokinase has high Km value that is high affinity for the substrate glucose
Glucokinase has high Km value that means low affinity for the substrate
The maximum reaction rate (Vmax) of hexokinase is low that means it gets saturated quickly by increasing glucose concentration
The maximum reaction rate (Vmax) of glucokinase is quite high, thus can handle larger glucose load resulting in a rapid conversion of glucose into usable energy.
Hexokinase is active even at low glucose levels
Glucokinase is active only at high glucose levels in liver
Is not inducible (*constitutive enzyme)
Is induced by glucose and insulin
Hexokinase is an allosteric enzyme with **allosteric site for regulation of enzyme activity
Glucokinase is not an allosteric enzyme
Feedback inhibition of hexokinase by
glucose 6 phosphate (product)
No direct feedback inhibition; not inhibited by glucose-6-phosphate
*Constitutive enzymes are always produced in constant amounts without regard to the physiological demand or the concentration of the substrate.
**Allosteric site: is the site other than the active site where effector molecule binds and regulated enzyme activity. This type of regulation is called allosteric regulation.

5 Differences between Genetics and Genomics (Genetics vs Genomics)

Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms.
Definition: Genomics is an multidisciplinary branch of biology focusing on the study the entire set of genes (genome) in an organism. You can watch the video also on Genetics vs genomics for better understanding
difference between genetics and genomics
Genetics
Genomics
Genetics is the study of single genes and their heredity and variation in organisms
Genomics is the study of all genes (the genome) of a person or  an organisms, including interactions of those genes with each other and with the person's/organisms environment.
Genetics is often a study of single gene or a few gene and their effects
Genomics is the study of complex diseases caused by multiple genes and environmental factors
Genetics is a classical branch of biology dates back to Mendel’s work on pea plants during early 1800, but rediscovered only during 1900.
Genomics is a much newer field flourished within last two decades due to technical advances in DNA sequencing and computational biology.
In 1906, William Bateson coined the term  “genetics” for the discipline of biology specifically dedicated to study heredity and variation.
The term genomics was coined in 1986 by Tom Roderick, a geneticist at the Jackson Laboratory in Maine, during a meeting about the mapping of the human genome.
Examples of genetic or inherited disorders include cystic fibrosis, Huntington's disease etc caused by mutation in a single gene
Genomics includes the scientific study of complex diseases such as heart disease, obesity, asthma, diabetes and cancer. (Multi gene diseases)
Primarily focussing on the study and treatment of single gene inherited disorders
Primarily focussing on the study and treatment of complex diseases caused by multiple genes and environmental factors
Genetics uses crossing, genomic mutation, recombination etc to study a trait associated with a gene
Genomics uses a combination of recombinant DNA, DNA sequencing methods, and bioinformatics to sequence, assemble and analyze the structure and function of genomes.

Difference between Oomycetes and True fungi (Oomycetes vs True Fungi)


Fungi are a group of microscopic as well as macroscopic, spore bearing, chlorophyll lacking, filamentous and heterotrophic thallophytes which reproduce asexually and sexually. Fungi are classified into slime moulds, oomycetes and true fungi. The Oomycetes (water moulds) are primarily aquatic fungi live as saprophytes or parasites. Although oomycetes morphologically similar to true fungi and exhibit absorptive nutrition and thus long classified with them, following features show that there are profound biological differences between oomycetes and true fungi.

Oomycetes
True fungi
Diploid somatic thallus
Haploid somatic thallus
Cellulose cell wall
Chitin present, No cellulose cell wall
Mitochondria cristae, tubular
Mitochondria cristate, plate like
Hydroxyprotine wall protein present
Hydroxyprotine wall protein absent
Lysine biosynthesis  Like plants, use diamino pimelic acid pathway
Like animals, use aminoadipic acid pathway
Oomycetes vs True fungi 

1. Somatic phases of oomycetes are diploid, whereas it is haploid in true fungi.

2. Meiosis occurs in developing sex organs or gametangia

3. Many produce egg cells during sexual reproduction. They are also known as egg fungi.

4. Most members produce swimming biflagellate zoospores with an anterior tinsel flagellum and a posterior whiplash flagellum.

5.The cell wall is mainly cellulosic in composition rather than chitionous as is the case in true fungi.

7. The vegetative thallus resembles the algal thallus in general construction.

8.The hyphal walls off oomycetes contain aminoacid hydroxyprotine which is not found other fungi, but is characteristic of the cell walls of green algae.

9. A number of biochemical synthetic pathways in the oomycetes are very different than those present on all other true fungi. Oomycetes like the plants synthesise lysine using diaminopimelic acid pathway rather than through the aminoadipic acid pathway.

10. Oomycetes have tubular mitochondrial cristae. All other fungi have plate like mitochondrial cristae.

11.Sexual reproduction in oomycetes in oogaamous. It takes place by gametagial contact resulting in a characteristic thick walled resting spore, called an oospore.
