Answer: The shape of an enzyme determines which reaction it can catalyze.
Explanation: The shape of an enzyme is very important because it has a direct effect on how it catalyzes a reaction. An enzyme's shape is determind by the sequence of amino acids in its structure, and bonds which then form between the atoms of those molecules. There are steps of the catalytic cyle of an enzyme and are as follows:
1. The enzyme has an empty active site and is available.
2. The substrate binds to the enzyme with induced fit.
3. The substrate is change to the products.
4. Finally the enzyme releases the products.
Hope this helps.
The proteins that catalyze the biochemical reactions are called enzymes. The enzyme shape determines the type of reaction it will catalyze. Thus, option 3 is correct.
Enzymes are substances that are composed of proteins and take part in the biochemical reactions to speed up the product formation by reacting with the substrate.
The enzymes are specific and bind to a substrate only if they match with the correct shape and size resulting in a complex formation. The enzymes have a particular shape that cannot be changed.
The shape of the enzyme is a determining factor for product formation as the enzyme-substrate complex forms only if the enzyme (key) and substrate (lock) should match.
Therefore, in option 3. the shape of the enzyme plays an important role.
