Chapter 8 Essay Questions. 1. Describe the chemistry of two types of enzymes and explain how the apoenzyme forms. 2. Describe the roles played by ATP and NAD in metabolism. 3. Name the major ways that substrate-level phosphorylatin is different from oxidative phosphorylatin. 4.
Enzymes help by catalyzing (speeding up) the reaction and intern lowering the activation energy required for the reaction to occur. Molecules called substrates bind with enzymes during reactions. However each enzyme has a very specific purpose.Essay The Effect Of Metabolism On The Human Body. shape as they are produced Enzymes Enzymes are very important catalysts for biochemical reactions. There are about 40,000 thousand different enzymes in a human cell. Enzymes take part in the reaction this is how they provide an alternative reaction pathway.Enzyme activity easily explained in questions and answers. Study and learn catalysis, enzymes, the enzyme-substrate complex, cofactor and allosterism.
Enzymes can speed up chemical reactions in several ways. For example, an enzyme may bring two reactant molecules close together and may properly orient them to react. Whatever the method, the result is that the enzyme lowers the activation energy for the reaction without increasing the temperature or pressure inside the cell (“Immobilized Enzymes Can Check Bioterrorism, 2003).
Enzymes help speed up chemical reactions in the body. They affect every function, from breathing to digestion. Lipases, for example, help digest fat. Enzymes only work in certain conditions. If.
Essay 1666 Words 7 Pages Introduction Enzymes are macromolecules that act as a catalyst, and it’s a chemical agent that accelerates the reaction without being consumed by the feedback or the results (Campbell and Reece, 2005).
Enzymes are sensitive. Each enzyme acts at a specific temperature, specific pH, and on a specific substrate (food upon which the enzymes act). For example, salivary amylase (found in the saliva of the mouth) works best at neutral pH, whereas gastric enzymes work best in acidic medium, and the intestinal or pancreatic enzymes work best in basic medium.

Enzymes are shape specific, which means only substrate molecules with the corresponding shape will combine with the enzyme. This is known as the Lock and Key theory. So, because of this many different enzymes can be present in a cell, acting at the same time but not affecting each other.

Enzymes are biological catalysts (also known as biocatalysts) that speed up biochemical reactions in living organisms, and which can be extracted from cells and then used to catalyse a wide range of commercially important processes. This chapter covers the basic principles of enzymology, such as classification, structure, kinetics and inhibition.
