Plant cells have mitochondria, which use glucose to produce ATP. Where does the glucose originate?

Romashka [77]

Plant produces glucose in the chloroplast through the process of photosynthesis. Calvin cycle is basically the biological process through which glucose is produced. The steps involved are as follows:

1. Absorbed CO2 is added to RuBP and 6C sugar is formed.

2. Breaking of 6C sugar into two 3-phosphoglycerate molecules

3. ATP gives phosphate group to form 3-phosphoglycerate which is later on converted into 1,3-biphosphoglycerate.

4. Electons are required by 1,3-biphosphoglycerate to an aldehyde called glyceraldehyde-3-phosphate or G3P and these electrons are donated by NADPH

5. Enzyme aldolase uses two molecules of G3P to produce 6 C sugar called fructose-1,6-biphosphate which is further converted to fructose-6-phosphate

6. Enzyme isomerase converts fructose-6-phosphate to glucose-1-phosphate
