Quick student answer
Which of the following is the primary pigment involved in photosynthesis?
Direct answer
Chlorophyll a is the primary pigment that absorbs light energy for photosynthesis.
Key terms
- Dehydrogenase: An enzyme that catalyzes the removal of hydrogen from a substrate, facilitating electron transfer in metabolic processes.
- NADP+: Nicotinamide adenine dinucleotide phosphate, a coenzyme that acts as an electron carrier in photosynthesis.
Common trap
Misunderstanding the role of chlorophyll: Emphasize that chlorophyll a is the main pigment responsible for capturing light energy in photosynthesis.
