G3P is converted into glucose phosphate in:
Correct answer: B. Chloroplast
- A. Mitochondria
- B. Chloroplast
- C. Golgi apparatus
- D. Endoplasmic reticulum
Explanation
The correct answer is chloroplast. In the chloroplast, G3P (glyceraldehyde-3-phosphate) is a product of the Calvin cycle, which is part of photosynthesis. This molecule is subsequently used to form glucose phosphate, which can then be converted into glucose and other sugars. The conversion takes place in the stroma of the chloroplast.The other options are associated with different cellular functions. Mitochondria are involved in cellular respiration, not photosynthesis. The Golgi apparatus processes and packages proteins and lipids, and the endoplasmic reticulum is involved in protein and lipid synthesis, neither of which is directly related to the conversion of G3P to glucose phosphate.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
