Question

During glycolysis, the addition of a new phosphate group on to a substrate can be catalyzed by which class(es) of enzymes? Kinase and phosphorylase Kinase and transferase Mutase and Isomerase Phosphorylase and Mutase QUESTION 17 Which of the following factors makes hydrolysis of acetyl coA a favorable process? Enol-keto tautomerization Increased delocalization of the pl-cloud Change of non-aromatic structure to aromatic structure Separation of like charges

Answer 1

1. The phosphate group onto the substrates are added by the kinase and the phosphorylase enzymes. For example, hexokinase adds phosphate to glucose and glycogen phosphorylase adds phosphate to the glucose molecule that is cut from the glycogen. Hence the correct answer is:. Kinase and phosphorylase.

2. The keto enol tautomerism helps in the acetyl coa hydrolysis. Hence the correct answer is: enol-keto tautomerisation.

3. Substrate level phosphorylation is the formation of ATP or GTP in the reaction. Hence the answer is: step 9.

4. The amino acids that bring kinks in the protein by intercalation are glycine and proline. Hence the correct answer is PROLINE.

5. Proteins interact with DNA by head to tail homodimers.
