Explanation:

Question 18

The equation \( 6CO_2 + 6H_2O + \text{light} = C_6H_{12}O_6 + 6O_2 \) represents photosynthesis. Photosynthesis occurs in chloroplasts. Mitochondria are for cellular respiration, ribosomes for protein synthesis, and cell membranes have other functions. So the correct organelle is chloroplasts.

Glycolysis is the first step of cellular respiration (and also part of anaerobic respiration). It occurs in the cytoplasm and breaks down glucose into pyruvate, producing a small amount of ATP. Alcohol fermentation and lactic acid fermentation are anaerobic pathways (not same for all aerobic/anaerobic), and electron transport is part of aerobic respiration only. So glycolysis is the step common to all aerobic and anaerobic organisms.

ATP (Adenosine Triphosphate) is an energy - storing molecule with three phosphate groups. "Anaerobic" refers to processes without oxygen, "Catabolic" refers to breakdown reactions. So the energy - storing molecule with three phosphates is ATP.

Answer:

D. Chloroplasts
