Which is a role of photosystem I in the light reactions? A. To break down glucose molecules for more energy
B. To make energy-carrier molecules like ATP
C. To make energy-carrier molecules like NADPH
D. To supply energy for splitting the water molecules

C. To make energy-carrier molecules like NADPH

Explanation:

In the light reaction of photosynthesis, Photosystem I is the second photosystem which is known as plastocyanin-ferredoxin oxidoreductase or PSI takes place in green plants or other photosynthetic organisms.

It is a protein complex that utilizes the trapped light energy by chlorophyll to produce high energy carriers such as NADPH. NADPH synthesis is a primary role of the PSI.

Thus, C. To make energy-carrier molecules like NADPH

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
