Answer: Denaturing
Explanation: Enzymes are made of amino acids that are linked by bonds, amongst those bonds are hydrogen bonds that are very weak. High temperatures and low pH(acidity) breaks those bonds changing the molecular conformation of the enzymes. That way they denature and loss the ability to perform their functions. High temperatures and acidity alter the structure of their active site preventing the substrate from binding to them. While high temperatures denatures enzymes, low temperature renders them inactive.
It is the fraction of all chromosomes in the population that carry that allele.
<span>A person who has rh- blood can develop rh agglutins through;
1. Pregnancy.
2. Transfusion.
3. Exposure to blood.
Agglutination is termed as clumping of particles. It is the process which occurs when an antigen is mixed with its corresponding antibody known as isoagglutinin.
When people are being given blood transfusion of wrong blood group then the antibodies will react incorrectly with the transfused blood group, then the erythrocytes clump up and stick together which causes them to agglutinate.</span>
Answer:
The correct answer will be option-A
Explanation:
The citric acid cycle is the cyclic chain of reactions taking place as a phase of the cellular respiration as it gets halted in the absence of oxygen.
The citric acid cycle converts the obtained acetyl-CoA to a usable form of energy in the form of ATP, NADH and FADH₂.
The citric acid cycle forms intermediates which are utilised by the organisms to synthesise the various biomolecules like amino acids, purines and pyrimidines.
The intermediates like alpha-ketoglutarate forms arginine, proline and glutamine whereas oxaloacetate forms asparagine and aspartate.
If bacteria do not receive the amino acids then they will synthesise the amino acids using intermediates of the citric acid cycle.
Thus, option-A is the correct answer.
