Statement I: | Low temperature preserves the enzyme in a temporarily inactive state whereas high temperature destroys enzymatic activity because proteins are denatured by heat. |
Statement II: | When the inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme, it is known as competitive inhibitor. |
Statement I: | A protein is imagined as a line, the left end represented by first amino acid (C-terminal) and the right end represented by last amino acid (N-terminal). |
Statement II: | \(\alpha\) type and two subunits of ẞ type.) | Adult human haemoglobin, consists of 4 subunits (two subunits of

1. | It breaks down when iodine reacts with it. |
2. | It is a disaccharide. |
3. | It is a helical molecule. |
4. | It does not contain complex helices and hence cannot hold iodine molecules. |
Statement I: | Amino acids have a property of ionizable nature of –NH2 and –COOH groups, hence have different structures at different pH. |
Statement II: | Amino acids can exist as Zwitterionic form at acidic and basic pH. |
