Glycolysis itself yields two ATP molecules, so it is the first step of anaerobic respiration. , the product of glycolysis, can be used in to produce ethanol and + or for the production of lactate and NAD+. The production of NAD+ is crucial because glycolysis requires it and would cease when its supply was exhausted, resulting in cell death. A general sketch of the anaerobic steps is shown below. It follows Karp's organization.
Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.
Photosynthesis & Cellular Respiration - Biology Junction
Respiration occurs in your cells and is fueled by the oxygen you inhale. The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.
Difference Between Photosynthesis and Cellular Respiration
Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the . Anaerobic respiration leaves a lot of energy in the ethanol or lactate molecules that the cell cannot use and must excrete.
Cell Processes: Photosynthesis & Cellular Respiration
While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements through cellular respiration.
Photosynthesis is the process by which plant cells convert light energy from the sun into chemical energy, so as to create energy-rich carbohydrate molecules like glucose.
