Is it true that the process by which cells withdraw energy from glucose is called photosynthesis

The stated statement above is False. Respiration process and photosynthesis (food production of plants) are two different terms. During respiration of plants, simple food molecules like glucose (produced during food production of plants) are broken down and energy is released. We can therefore deduced that the process by which cells "withdraw" energy from glucose is called respiration' not photosynthesis. In photosynthesis, sugar (glucose) is produced which is converted into ATP during the process of cellular respiration.

No. Photosynthesis has to do with plants not cells. The process you are describing is the respiration process.
