Most of the biochemical pathways in living things are enhanced by the control proteins called . The efficiency of the enzyme-catalyzed reactions is often increased by the presence of helper molecules called coenzymes. A coenzyme present in every living cell is +. It participates in reactions in cell metabolism processes like . Another essential coenzyme is which also contributes to the electron transport process.

In photosynthetic organisms, the light energy drives the of . Much of the energy is used to reduce the coenzyme NADP+ to form , thereby raising it to a higher energy state. The energy of NADPH is then used in the as a part of the process of carbohydrate synthesis.

Zinc/cobalt carbonic anhydrase. We measure Reaction rates and products of both the zinc and cobalt forms of the enzyme using standard catalytic assays. These measurements tell us much about reaction mechanisms and how they vary between the zinc and cobalt versions of the enzyme. We also measure equilibrium constants for metal-ion binding by both Zn2+ and Co2+ and compare the affinities of the enzyme for binding the two metals.

Cadmium carbonic anhydrase. The cadmium protein is isolated by standard chromatographic methods. Standard genetic methods generate sufficient quantities of the protein for further analysis, including standard catalytic assays. This protein also facilitates development of anti-sera for the cadmium carbonic anhydrase enzyme, to be used for the study of regulation (see below). The enzyme's structure is also studied: the active site is characterized by 113Cd NMR , and, where appropriate, detailed structural characterization is attempted by X-ray or NMR methods.

The stomach is an important part of the digestive system. Firstly it secretes HCL which kills bacteria and other harmful organisms preventing food poisoning and it also provides the optimum conditions for the enzyme pepsin to work in (pH 1.5 - 2). In addition, the stomach secretes pepsin which starts the digestion of proteins into polypeptides and amino acids. Theses can then be absorbed by the villi in the small intestine.

What role do enzymes serve in cellular respiration

The small intestine is where the final stages of digestion occur. The intestinal wall secretes enzymes and it also receives enzymes from the pancreas. However the main function of the small intestine is the absorption of the small food particles resulting from digestion. It contains many villi which increase the surface area for absorption.
