Question

question 10
glycolysis occurs in what part of the cell?
mitochondria
plasma membrane
cytoplasm
nucleus
question 11
meiotic division occurs in
body cells and primitive sex cells.
primitive sex cells.
body cells.
somatic cells.
question 12
proteins that act as catalysts are called
substrates.
enzymes.
inhibitors.
activators.

Explanation:

• Question 10: Glycolysis is the first - stage of cellular respiration and occurs in the cytoplasm of the cell. Mitochondria are involved in later stages of respiration, the plasma membrane is for cell - environment interactions, and the nucleus contains genetic material.
• Question 11: Meiotic division is a type of cell division that occurs in primitive sex cells to produce gametes. Body cells (somatic cells) undergo mitotic division.
• Question 12: Enzymes are proteins that act as catalysts in biological reactions, increasing the rate of reactions without being consumed. Substrates are the reactants on which enzymes act, inhibitors slow down enzyme - catalyzed reactions, and activators enhance enzyme activity.

Answer:

• Question 10: C. cytoplasm
• Question 11: B. primitive sex cells.
• Question 12: B. enzymes.
