vitamins
What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.
Protects the body destroys bacteria and tumor cells?
T cells are made in the red bone marrow but specialize into t cells outside the marrow in the thymus, hence the T in Tcells. two types of t cells are cytotoxic effector cells and helper t cells. think of cytotoxic t cells as the drunk guy in the bar that wants to fight everyone (and is a good fighter by the way) and the helper t cells are the friends who show him who to fight and provides him with the weapons to fight. CTC can attach to and destroy cells carrying antigens Helper T cells 1. present antigen to CE cells and plasma B cells to activate them into action and 2. produe powerful immune protein called cytokins which can stimulate the lymphocyte cell disvision.
Immunity uses helper cells and killer cells to identify and destroy abnormal cells?
Cellular immunity uses helper cells and killer cells to identify and destroy abnormal cells.
Do helper t cells have a cell membrane?
All cells have a cell membrane.
What is a non-protein helper of an enzyme molecule called?
A non-protein helper of an enzyme molecule is called a cofactor. Cofactors can be either inorganic ions (like metal ions) or organic molecules (like coenzymes) that assist enzymes in catalyzing chemical reactions.
What is the relationship between coenzymes and vitamins?
An enzyme is a protein molecule that acts as a catalyst to speed up the rate of a reaction. A coenzyme is an organic molecule that serves as an enzyme helper (aka cofactor). A vitamin is a group of unrelated molecules used in the making of certain coenzymes. Like enzymes, cells use inorganic cofactors, coenzymes, and vitamins repeatedly until these molecules are worn out or destroyed.
Why co factor more stable than enzyme?
A cofactor is a non-protein chemical compound that is bound to a protein. The protein they are bound to are often enzymes. Cofactors are considered "helper molecules" that assist in biochemical transformations. An enzyme are large biochemical molecules that is responsible for many chemical interconversions that sustain life. A cofactor is more stable because it tightly binds to the enzymes to make them stronger.
Which term refers to a macromolecule that attaches to an enzyme and plays a helper role in catalysis?
Cofactor

Why are helper t-cells required in an immune attack?
Helper T cell helps to develop anti viral protein interleukin
What is a student helper called?
accomplice, helper-in-crime
Is a CD4 molecule also a type of antigen?
CD4 is a glycoprotien expressed on the surface of Helper T Cell
