The process X is cellular respiration. It involves the use of oxygen to break down a monosaccharide to produce ATP and ADP.
The metabolic processes taking place in a plant cell are shown in the image in the question. We are supposed to identify;
- The process Y and the organelle where it occurs
- The molecule Z
- The process X
Firstly, let us recall that the process X involves the combination of carbon dioxide and water to produce a monosaccharide. This is the process of photosynthesis and it occurs in the chloroplasts.
When there is a high level of glucose in the body, the molecule acetyl co-A(molecule Z) could be converted into triglycerides. The process X involves the use of oxygen to break down a monosaccharide to produce ATP and ADP. The process involved is cellular respiration.
