Metabolic Pathways | MCQs

Explanation

Enzymes (e.g., ribosomes, polymerases) catalyze the assembly of proteins from amino acids during translation.

While enzymes assist in building various biomolecules, their most direct and universal role is in protein synthesis.

Explanation

Bioenergetics is the process by which living organisms convert free energy into different forms.

Such as light energy to chemical energy in photosynthesis, or chemical energy from nutrients to kinetic energy in cellular respiration.

This conversion is essential for maintaining life and supporting various cellular activities.

Explanation

In the human body, there are more than 1,000 known enzymes.

These enzymes play essential roles in catalyzing biochemical reactions.

Explanation

There are indeed two main types of metabolic reactions:

1. Anabolic reactions (building molecules, requiring energy)
2. Catabolic reactions (breaking down molecules, releasing energy)

Explanation

Metabolic reactions are both constructive (anabolic) and destructive (catabolic) reactions.
