Question

Choose the CORRECT statement about enzymes below. Group of answer choices Enzymes raise the activation energy needed in a chemical reaction
Enzymes slow down the rate of chemical reactions
Enzymes function best at specific pH and temperatures
Enzymes are carbohydrates and store short term energy

Answer 1

Enzymes are biological catalysts that catalyzes important reactions.

Explanation:

Enzymes acts on specific substrate and forms products.

Enzymes has following properties-

1. Enzymes decreases the activation energy of the chemical reaction.

2. Enzymes increases the rate of reaction, thus reactions will occur at a faster rate compared to reactions without enzymes.

3. Enzymes are proteins that work as optimum pH and temperature.

So, the correct option is- enzymes function best at specific pH and temperature.

Answer 2

C. Enzymes function best at specific pH and temperatures is correct.

This is the correct statement.

Explanation:

Enzymes are proteins that reduce the activation energy of a reaction.

In this way, enzymes increase the speed of a reaction and help it to run faster.

Enzymes work best in specific temperature and pH ranges, and suboptimal conditions can result in the loss of an enzyme's ability to bind to a substrate.

Temperature: An increase in temperature generally speeds up a reaction, and a drop in temperature slows down a reaction.

To break down a protein into its amino acids, you need enzymes. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions to occur anywhere in life. They are proteins, not carbohydrates .
