Question

how many atp are required for synthesis of one molecule of glucose in c4 pathway?
​

Answer 1

Answer:

Most of the plants that are adapted to dry tropical regions have the C

4

pathway. e.g. Sugarcane, Maize, Sorghum,etc. These plants are known as C

4

plants.For the formation of sugars, C

4

plants undergo C

4

cycle as well as C

3

cycle or Calvin cycle. In these plants double fixation of carbon dioxide occurs.

ATP consumed in C

4

plants:

C

4

cycle - 2 ATP per CO

2

fixed

C

3

cycle - 3 ATP per CO

2

fixed

Total - 5 ATP per CO

2

fixed

Thus, to form one molecule of glucose or to fix 6 CO

2

, 6 X 5 = 30 ATP are consumed.

Answer 2

Explanation:

38 Atp are required for synthesis
