This flow of hydrogen ions across the membrane through ATP synthase is called chemiosmosis. Chemiosmosis (Figure 4.19 c) is used to generate 90 percent of the ATP made during aerobic glucose catabolism. The result of the reactions is the production of ATP from the energy of the electrons removed from hydrogen atoms.

Features of Enzyme Catalyzed Reactions Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Enzymes are biological catalysts Enzymes are the catalysts involved in biological chemical reactions. They are the “gnomes” inside each one of us that take molecules like nucleotides and align them together to create DNA, or amino acids to make proteins, to name two of thousands of such functions.

Enzymes as Catalysts. Enzymes are proteins that have a specific function. They speed up the rate of chemical reactions in a cell or outside a cell. Enzymes act as catalysts; they do not get consumed in the chemical reactions that they accelerate.

Page 10: Animated representation of β-galactosidase activity with ONPG The difference between lactose and ONPG (for the purposes of our assay) is that, unlike glucose, the product ONP can be measured after cleavage – it has a yellow color (Fig. ... The color means that the molecule absorbs light at specific wavelengths.

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. ... The enzyme active site is the location on the enzyme surface where substrates bind, and where the chemical reaction catalyzed by the enzyme occurs.

Enzymes often act by coupling an endergonic reaction to the exergonic hydrolysis of ATP.

ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released by splitting these bonds, for example in muscles, by producing work in the form of mechanical energy.
