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.
Glycolysis. Cells harvest the energy contained in the chemical bonds of glucose in a very controlled, step-by-step series of reactions that release small amounts of energy during each biochemical reaction. Glycolysis is the first step of cellular respiration, where a molecule of glucose is split to release energy.The process of glycolysis is an enzyme controlled, four-step reaction that occurs in the cytoplasm of the cells:lycolysis is the first step of cellular respiration, where a molecule of glucose is split to release energy.
