Non-protein compounds called co-factors are required for some proteins in order to facilitate enzymatic activity. Common examples of co-factors are metal ions (Ca2+, Mg2+ etc.), organic co-factors such as heme (in hemoglobin), among others.

What 2 fat-based molecules make up part of the structure of the plasma membrane?
phospholipid and cholesterol
Is the non protein part of an enzyme will attach with enzyme after making product?
Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions.[1][2] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.Like all catalysts, enzymes work by lowering the activation energy (Ea‡) for a reaction, thus dramatically increasing the rate of the reaction. Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions. As with all catalysts, enzymes are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions. However, enzymes do differ from most other catalysts by being much more specific. Enzymes are known to catalyze about 4,000 biochemical reactions.[3] A few RNA molecules called ribozymes also catalyze reactions, with an important example being some parts of the ribosome.[4][5] Synthetic molecules called artificial enzymes also display enzyme-like catalysis.[6]Enzyme activity can be affected by other molecules. Inhibitors are molecules that decrease enzyme activity; activators are molecules that increase activity. Many drugs and poisons are enzyme inhibitors. Activity is also affected by temperature, chemical environment (e.g., pH), and the concentration of substrate. Some enzymes are used commercially, for example, in the synthesis of antibiotics. In addition, some household products use enzymes to speed up biochemical reactions (e.g., enzymes in biological washing powders break down protein or fat stains on clothes; enzymes in meat tenderizers break down proteins, making the meat easier to chew).
What is the relationship between chromosomes and DNA molecules?
Chromosomes are complete molecules of DNA and its attached proteins. A chromosome carries part or all of an organisms genes.
What are proteins that are transported in vesicles made by?
Transport vesicles play a key part in moving molecules to and from the membrane-confined chambers of the secretory pathway. Proteins are transported in vesicles; the proteins are made on the cytosolic side of membranes.
Functions of proteins in cell membrane?
Proteins can act as : Receptores, ones with active sites that can become functional; Recognition, especially glycoproteins; Transporter proteins, both active and passive transporters; Sturctural, maintaining the integraty of the membrane Some play a part in intracellular and extracellular signalling
What acts as proteins?
Proteins are part of the 4 main organic molecules, Carbohydrates, nucleic acids, lipids, and proteins. They are carbon based molecules that have an amino and carboxyl group.
What part of your diet contains molecules rich in nitrogen?
These are the proteins.
Which part of a chemical reaction is most changed by enzyme activity?
Reaction equilibrium
What part of the membrane helps large molecules pass through?
Globular proteins.
What part of the body has enzyme that begin the process of breaking down starch molecules?
The salivary glands have an enzyme called amylase that begins the breakdown of starch.
Which activity is part of inflammatory response?
Complement proteins signaling phagocytes
Peroxidase is an enzyme that breaks down hydrogen peroxide in cells It accomplishes this because of its structure What part of the enzyme is involved in catalytic activity?
active site
What 2 fat-based molecules make up part of the structure of the plasma membrane?
phospholipid and cholesterol
What part of the membrane helps large carbohydrate molecules enter the cell?
Globular proteins
