Question

1. a bodybuilder is getting ready to compete in a bodybuilding competition. he wants to take a supplement that will provide him with enzymes and instant energy. which two biomolecules does he need to focus on receiving?

a. carbohydrates c. proteins
b. lipids d. nucleic acids

1. an enzymes role is to ________ (speed up/slow down) reactions by ________ (increasing/decreasing) the energy required.

Explanation:

Question 2

To solve this, we analyze each biomolecule:

• Carbohydrates (A) provide instant energy (e.g., glucose).
• Proteins (C) often act as enzymes (biological catalysts).
• Lipids (B) are long - term energy storage, not for instant energy.
• Nucleic Acids (D) are for genetic information, not energy or enzymes.

So the two biomolecules are Carbohydrates and Proteins.

Enzymes are biological catalysts. Their role is to speed up chemical reactions. They do this by decreasing the activation energy (the energy required to start a reaction). If the activation energy is lower, the reaction can occur more easily and quickly.

Answer:

A. Carbohydrates, C. Proteins
