What are complex organic cofactors that are frequently derived from vitamins?
coenzyme
What Nonprotein molecules that join with enzymes temporarily during chemical reactions in cells?
Coenzymes and cofactors are non-protein molecules that temporarily bind to enzymes during chemical reactions in cells. They assist enzymes in their catalytic function by providing chemical groups or assisting in the transfer of electrons.
What are all cells derived from?
Existing Cells
Where do cofactors and coenzymes bind?
Cofactors and coenzymes typically bind to the active site of enzymes, where they assist in catalyzing biochemical reactions. Cofactors, which can be metal ions or small molecules, may bind permanently or transiently, while coenzymes, often derived from vitamins, usually bind temporarily and are altered during the reaction. Their presence is crucial for the proper functioning of enzymes, enhancing their ability to convert substrates into products.
New surface epithelial cells and epithelial cells lining the intestines are derived from where?
New surface epithelial cells are derived from stem cells located in the basal layer of the epithelium. Epithelial cells lining the intestines are derived from stem cells located in the intestinal crypts.
What cell is an antibody factory?
Plasma cells, which are derived from B cells.
Did lactase activity depend upon the presence of cofactors?
Yes, lactase activity depends on the presence of cofactors such as magnesium and zinc ions to function optimally. These cofactors help stabilize the enzyme structure and facilitate the breakdown of lactose into glucose and galactose. Without these cofactors, lactase activity may be reduced.
What is an inorganic cofactor?
An inorganic cofactor is a non-protein chemical compound that is essential for the biological activity of certain enzymes. These cofactors can be metal ions, such as zinc, magnesium, or iron, which assist in enzyme function by stabilizing structures, facilitating substrate binding, or participating in catalytic reactions. Unlike organic cofactors, which are often derived from vitamins, inorganic cofactors do not contain carbon and are typically involved in various biochemical processes. Their presence is crucial for maintaining proper enzymatic activity and overall metabolic function.
Transfer factors are derived from which cells?
Transfer factors can be derived from either spleen cells or blood cells. The factors are made completely from amino acids, which consist of carbon, hydrogen, oxygen and nitrogen.
How do enzyme cofactors and coenzymes differ?
Enzyme cofactors are inorganic ions or small molecules that assist enzymes in catalyzing reactions, while coenzymes are organic molecules, often derived from vitamins, that act as carriers of specific functional groups to help enzymes function properly. Cofactors are usually tightly bound to the enzyme, while coenzymes are loosely bound and may shuttle between enzymes to transfer functional groups.
What are stem cells derived from?
umbilical cord blood.
Is photovoltaic cells derived from living things?
Yes
