Question

1,336 minutes remaining | ① life __ without enzymes. ② enzymes __ the activation energy of a reaction. ③ the image shown here displays which kind of inhibitor? (reference ch6, slides #39 - 41).

Explanation:

1. Enzymes are crucial for life - sustaining reactions. Without them, the chemical reactions necessary for life would occur too slowly or not at all.
2. Enzymes function as biological catalysts that lower the activation energy required for a chemical reaction to proceed.
3. A competitive inhibitor binds to the active - site of an enzyme, competing with the substrate for binding. Based on the general knowledge of enzyme - inhibitor interactions and without seeing the full image details, this is a common characteristic of competitive inhibitors.

Answer:

1. would not be possible
2. lower
3. competitive inhibitor
