Enzymes that are functioning within the cell are called:
Correct answer: A. Endoenzymes
- A. Endoenzymes
- B. Exoenzymes
- C. Holoenzymes
- D. Both A & C
Explanation
Endoenzymes are enzymes that act within the cell, and their catalytic activity is confined to the interior of the cell. They are involved in intracellular processes, catalyzing reactions within the cell's cytoplasm or organelles. Enzymes involved in glycolysis, the Krebs cycle, or other metabolic pathways taking place inside the cell are considered endoenzymes.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
