B may d answer 4 following question
<span>During Glycolysis, one molecule of glucose is converted into two molecules of pyruvic acid in the cytoplasm of the cell. Pyruvic acid is then moved into the inner matrix of the mitochondria, which is the organelle within the cell responsible for the generation of energy. The pyruvic acid molecule is converted into acetyl Co-A, which is the molecule that enters the Krebs Cycle. In the Krebs Cycle, acetyl Co-A is attached to oxaloacetate acid to form citric acid; the Krebs Cycle is alternately known as the citric acid cycle.</span>
False. It's not always reliable. For example, in lab mice, saccharin has caused tumors. But for humans to get cancer from saccharin, we would have to take in astronomical levels of saccharin, which we, as humans, don't do.
Photosynthesis starts when a photon- a tiny packet of light is absorbing a molecule of chlorophyll.
