Answer:

Physical Change

Select the correct statements about glycolysis. a) Major products of glycolysis include pyruvate, ATP , and NADH . b) Glycolysis
dalvyx [7]

Answer:

a). Major products of glycolysis include pyruvate, ATP , and NADH

b) Glycolysis is the process by which glucose is converted to two molecules of pyruvate.

Explanation:

Glycolysis is a process in which a glucose molecule is broken down into two molecules of pyruvate. The process of glycolysis occurs without oxygen therefore it can occur in both aerobes and anaerobes.

The process of glycolysis occurs in the cytoplasm of the cell and the products of glycolysis are 2 molecules of pyruvate, 2ATP, and 2 NADH molecule. Then the pyruvate molecule gets into mitochondria which it's complete oxidation takes place. Therefore the right answer is a and b.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, use and produce a variety of molecules. Sort
Margaret [11]

Molecules brought in and used in the calvin cycle - Carbon dioxide (CO_2) , Ribulose bisphosphate (RuBP)

Molecules produced during the calvin cycle that leave the cycle - a few of the glyceraldehyde-3-phosphate (G3P), NADP+

Molecules used and regenerated within the calvin cycle - most of the Glyceraldehyde-3-phosphate (G3P) , NADPH

<u>Explanation:</u>

Calvin cycle is the light independent reaction that takes place in the stroma of the chloroplast. Calvin cycle uses ATP and NADPH produced during the light reaction. Calvin cycle occurs in 3 steps, they are:

1. Carbon fixation - (CO_2) combines with Ribulose bisphosphate (RuBP) to form 2 molecules of 3-phosphoglyceric acid (3-PGA).

2. Reduction - ATP and NADPH is used to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).

3. Regeneration - some G3P molecule form glucose while other regenerates to form RuBP acceptor.
