light strikes photosystem 2, exciting the electrons. The electron come from a water molecule that has been split into hydrogen and oxygen. That is the first reactant (water), and Oxygen gas is given off as the first product. The excited electrons then travel down a short electron transport chain, and while doing so they pump H+ molecules (hydrogen molecules) into the inner thylakoid space across the thylakoid membrane from the stroma. The electrons are then passed, at the end of the transport chain, to photosystem 1, where they are re-excited by light. The electrons are passed down another short electron transport chain, which pumps a few more H+ into the thylakoid space, then the electrons get passed to a molecule of NADP+, which is reduced to NADPH. NADPH is a product, NADP+ a reactant. The H+ in the thylakoid then diffuse back into the stroma through a molecule of ATP Synthase that is a channel through the memebrane of the thylakoid. As they pass through the ATP synthase, the H+ make the ATP Synthase go into it's active conformation so it is able to turn ADP into ATP. ADP is a reactant, ATP is a product. To sum it all up, H20, NADP+, and ADP are reactants, and oxygen, NADPH, and ATP are products.
Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. Together, these processes represent the flow of energy in living organisms.
Firstly in the light stage,or light dependant stage, the light causes water to split. When this happens half oxygen is released into the atmosphere and the rest is used for respiration. A number of protons are formed and they join a proton pool, electrons are formed and they are used to charge the chlorophyll. AN electron then follows 1 of 2 paths. Pathway one-cyclic electorn transport, energy is released+ADP+P to form ATP. Pathway 2- Non cyclic electron transport, here 2 electorns +nadp+ + a proton are used to form NADPH. Then in the Darkstage which occurs in the stroma, ATP and NADPH are brought here and they drop off energy 2 electrons and a proton. ADP + P and NADP+ get recycled to the light stage. CO2 + 2 electrons and a proton then form glucose (C6H12O6) and that's that.
Food energy which is primarily glucose is broken down to form ATP during cellular respiration. Cellular respiration is an efficient way for cells to harvest energy stored in food. Glucose sugars and oxygen are broken down through metabolic reactions to release stored energy with carbon dioxide and water as waste products.

The products of photosynthesis are used in the process of cellular respiration and vice versa.
Photosynthesis makes glucose molecules, but cellular respiration breaks them down.
Sugar!
Yes, cellular respiration can occur without photosynthesis. Cellular respiration is the process by which cells generate energy from food molecules, while photosynthesis is the process by which plants convert sunlight into energy. Organisms like animals rely on cellular respiration to produce energy without needing photosynthesis.
The reverse of photosynthesis is cellular respiration.
Cellular respiration is the process that "withdraws" the energy.

The products of photosynthesis are used in the process of cellular respiration and vice versa.
The process that is the opposite of photosynthesis is cellular respiration. In cellular respiration, organisms break down glucose to produce energy, carbon dioxide, and water. This process releases energy stored in glucose and is used by all living organisms to power their cellular functions.
There is no replication of the DNA in cellular respiration or photosynthesis. In cellular respiration, you have biological oxidation of the glucose molecule. In case of the photosynthesis you have the reverse process that takes place.

Photosynthesis in the chloroplast is a process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Cellular respiration in the mitochondria is a process by which cells break down glucose to produce energy in the form of ATP, with oxygen being used as a final electron acceptor. Essentially, photosynthesis stores energy while cellular respiration releases energy.
No, both photosynthesis and cellular respiration occur in plants as well as in other organisms such as bacteria, fungi, and animals. Photosynthesis is the process by which plants use sunlight to produce energy, while cellular respiration is the process by which organisms use oxygen to break down glucose and produce ATP for energy.
