Cofactor is a non-protein, inorganic enzyme helper. An example of a cofactor is metal ions.
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.
T helper 1 cells activate and assist in the activation of T cells by releasing signaling molecules called cytokines. These cytokines help stimulate T cells to multiply and become more effective in fighting off infections. Additionally, T helper 1 cells can directly interact with T cells to provide necessary signals for their activation and function.
A helper T-cell is activated in the immune response process when it recognizes a specific antigen presented by an antigen-presenting cell. This interaction triggers the helper T-cell to release signaling molecules that coordinate and enhance the immune response.
Helper T cells are activated in the immune response when they encounter an antigen-presenting cell that displays a specific antigen on its surface. This interaction triggers the helper T cell to become activated and release signaling molecules that help coordinate the immune response.
T helper cells are activated in the immune response process when they encounter antigens presented by antigen-presenting cells, such as dendritic cells. This interaction triggers the T helper cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.
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.
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.
A magician's helper or assistant is sometimes called a famulus.
No, a CD4 molecule is not an antigen. CD4 is a protein found on the surface of helper T cells, a type of immune cell that plays a crucial role in the adaptive immune response by helping to coordinate immune responses. Antigens are molecules that can be recognized by the immune system, such as proteins on the surface of pathogens or foreign substances.
The name of a King's helper depends on where they reign. A common name for this helper is Governor.
A cofactor refers to a macromolecule that attaches to an enzyme to assist in catalysis. This can be a metal ion or a coenzyme.

Bart's dog is called Santa's Little Helper. Funny name!
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.
