Answer 23. Enzymes
Ribozymes, also called catalytic RNA are the enzymes present in Ribosome which joins amino acids to form protien.
Answer 24. NADH
- Formation of Acetyl coenzyme A is also called Oxidative decarboxylation.
- Pyruvate, which is formed by the glycolytic catabolism of carbohydrates in the cytosol, after it enters mitochondrial matrix undergoes Oxidative decarboxylation by a complex set of reactions catalysed by pyruvate dehydrogenase.
- The reaction is as follows

QUESTION 25 Which of the following are true about kinases? The products of the reactions they catalyze have less free energy than the substrates, even when ATP is produced O kinases are enzymes that catalyze ATP hydrolysis in order to move vesicles along the microtubules The acivity of kinases cannot be regulated, which is why reactions catalyzed by kinases tend to be irriversible.
