PHOTOSYNTHESIS. INTRODUCTION. Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms.hotosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose.
Glycolysis. Glycolysis, part of cellular respiration, is a series of reactions that constitute the first phase of most carbohydrate catabolism, catabolism meaning the breaking down of larger molecules into smaller ones.The word glycolysis is derived from two Greek words and means the breakdown of something sweet.he pyruvate end product of glycolysis can be used in either anaerobic respiration if no oxygen is available or in aerobic respiration via the TCA cycle which yields much more usable energy for the cell.
1. glycolysis-starts cellular respiration by breaking glucose down into pyruvate. (small amount of ATP is made as well). 2. citric acid cycle (krebs cycle) - completes the breakdown of glucose by decomposing a derivative of pyruvate to carbon dioxide. also, this stage supplies oxidative phosphorylation with electrons.he three stages of cellular respiration are glycolysis, the Krebs  Cycle, and the electron transport chain. The first stage happens in  the cytoplasm while the last two occ â¦ urs in the mitochondria. 1 person found this useful. Judy Olmsted. 79,343 Contributions. Retired college science professor.
