Plant cells manufacture glucose through photosynthesis. When glucose is present in excess, plants store it by using it to synthesize chains of sugar molecules called starches. These starches form an important component of the human diet. Features Each molecule of glucose has a hexagonal ring structur...
Starches are similar in some respects to another polymer called cellulose; both starch and cellulose are long chains of glucose molecules. In cellulose, however, the glucose molecules are in a slightly different configuration called beta-glucose, so when they form bonds, each glucose molecule is up...
How do endothelial cells control vasoconstriction? Where in a plant cell is glucose produced? What happens to glucose in the kidneys? How does sugar or protein enter the matrix if the inner membrane of the mitochondria is impermeable? Explain the chemical structure of glucose. What happens to gl...
How does a plant cell function? In which way are plants and animals different in how they obtain energy? How is the energy produced by respiration stored? How is O2 a pi electron acceptor? Describe how O2 moves from the atmosphere to the mitochondria in the cells in the body and how it...
Insulinis a hormone produced by thepancreas. It helps your cells use the glucose in your blood. In type 1 diabetes, the pancreas stops making insulin or makes very little.2 That makes frequent testing important. It helps ensure you have enough insulin to keep your blood sugar levels stable....
Insulin is a simple protein normally produced by the pancreas. In people withdiabetes, the pancreas is damaged and cannot produce insulin. Since insulin is vital to the body's processing of glucose, this is a serious problem. Many diabetics, therefore, must inject insulin into their bodies dail...
Building muscle means more than going to the gym -- it means lifting, eating, and resting the right way. Here's how to build muscle, according to experts.
They provide additional evidence to support their earlier assertion [Ozcan S, et al. Proc Natl Acad Sci USA 1996;93:12428-12432 (Ref. 2)] that glucose transport via Snf3 and Rgt2 is not involved in glucose sensing but, rather, that these proteins behave like glucose receptors. Other ...
Aerobic cellular respiration is the process by which cells use oxygen to help them convert glucose into energy. This type of respiration occurs in three steps: glycolysis; the Krebs cycle; and electron transport phosphorylation. Oxygen is necessary for c
Insulin is a hormone produced by the beta cells in the pancreas and is essential for the regulation of the metabolism of proteins, fats, and carbohydrates. The hormone is most known for it's role in maintaining blood glucose levels by promoting sugars absorption into the muscles, fat, and ...
