Question

1. which of the following organelles is correctly matched with its product?

a. nucleolus -- dna
b. mitochondria -- atp
c. golgi apparatus -- lipid
d. smooth endoplasmic reticulum -- protein

Explanation:

• Nucleolus: It is involved in ribosome synthesis, not directly related to DNA production. DNA is mainly replicated and synthesized in the nucleus.
• Mitochondria: Known as the "power - house" of the cell. Through cellular respiration (especially oxidative phosphorylation), mitochondria produce ATP (adenosine triphosphate), which is the energy currency of the cell.
• Golgi apparatus: Its main functions include modifying, sorting, and packaging proteins and lipids. For example, it can add sugar groups to proteins (glycosylation) and package them into vesicles for transport.
• Smooth endoplasmic reticulum: Involved in lipid synthesis (such as steroid hormone synthesis in some cells) and detoxification processes. Protein synthesis is mainly associated with the rough endoplasmic reticulum (which has ribosomes attached).

Answer:

B. mitochondria — ATP
