PGA ( Phosphoglyceric acid) is a first stable product of photosynthesis which under goes reduction. Six molecules of 3-PGA is reduced to six molecules of a chemical compound called glyceraldehyde 3-phosphate (G3P). In this conversion; six molecules of both ATP and NADPH are used. In this reduction reaction, there is gain of electrons by 3-PGA. NADPH is oxidized to NADP+ to give elections and energy is given by ATP.
D. Certain genes are turned on and others are turned off; this action produces adult cells that are specialized
For mutations to affect an organism's descendants, they must: 1) occur in cells that produce the next generation, and 2) affect the hereditary material. Ultimately, the interplay between inherited mutations and environmental pressures generates diversity among species.
