How can i Describe how the products of the light phase of photosynthesis are used to form a glucose molecule and how this molecule is broken down in the cell of a plant to release energy. Thanks in advance
Since this is not my area of expertise, I searched Google under the key words "photosynthesis" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
Don't just copy the material. Express the ideas in your own words. Although this will take more time and effort, you will learn more.
P.S. How is this math?
During respiration
To describe how the products of the light phase of photosynthesis are used to form a glucose molecule and how this molecule is broken down in the cell of a plant to release energy, let's break it down into two parts: the formation of glucose and its subsequent breakdown.
1. Formation of glucose:
During the light phase of photosynthesis, the energy from sunlight is captured by the chlorophyll in the chloroplasts of plant cells. This energy is used to split water molecules, producing oxygen as a byproduct, and generating energy-rich molecules called ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).
With the help of ATP and NADPH, the second phase of photosynthesis, known as the dark or Calvin cycle, takes place. In this cycle, carbon dioxide molecules from the air are combined with the ATP and NADPH to form glucose. This process is called carbon fixation, where the carbon from carbon dioxide is fixed into organic molecules like glucose. Glucose serves as an energy-rich carbohydrate that plants can use for various metabolic processes.
2. Breakdown of glucose to release energy:
Once glucose is formed in the plant cell, it can be broken down through a process called cellular respiration to release usable energy. Cellular respiration occurs in the mitochondria of the plant cells and involves the following steps: glycolysis, the Krebs cycle (or citric acid cycle), and the electron transport chain.
During glycolysis, glucose is converted into two molecules of pyruvate, producing a small amount of ATP. The pyruvate then enters the mitochondria, where it goes through the Krebs cycle. In this cycle, the pyruvate is further broken down, generating more ATP and electron carriers such as NADH (reduced form of NAD+) and FADH2 (reduced form of FAD).
Finally, the electron carriers produced in the previous steps enter the electron transport chain, where a series of reactions occur, ultimately leading to the production of a large amount of ATP. This process is known as oxidative phosphorylation.
Overall, the breakdown of glucose through cellular respiration allows the plant cell to extract the energy stored in the glucose molecule, which can then be used for various metabolic activities, such as growth, repair, and reproduction.
Understanding these processes can be further enhanced by studying the details of photosynthesis and cellular respiration in biology textbooks or online resources.
