Question

Can you please answer questions 1,2,3 to the best of your abilities ! I need help with this homework

Part I. Do one of the following questions in the space provided. If you need more than two or three sentences, that's probably too much. (5) 1. List three unique properties that inter-molecular hydrogen bonding gives to water, and explain why any one of them is important for a cell's physiology 2. Mechanistically, why does phosphorylation change the activity of an enzyme? Part II. Do one of the following questions in the space provided. If you need more than two or three sentences, that's probably too much. (5) 3. List three of the general mechanisms used by enzymes that lower the activation energy of the catalyzed reaction.

Answer 1

1. Liquid nature to the water, which acts as medium for all enzymatic reactions. 2. High heat of vapourization that prevents water loss from cell even sudden increase of the temperature and 3. High boiling point and polar nature prevent dehydration and support enzyme catalysis

2. Phosphorylation increses the charge on the protein or enzyme, which facilitates thermodynamically favourable active folding in the enzyme, that increses the chance of increased catalysis

3. Metal ion catalysis, Covalent catalysis and electro static or ionic catalysis
