enzymes review part one

which statement about enzymes is NOT correct?

Enzymes are destroyed when they are used and must be synthesized for each reaction*

which statement best describes enzymes?

They influence the rate of chemical reactions

the sweet taste of freshly picked corn is due to the high sugar content in the kernels. enzyme action concerts about 50% of the sugar to starch within one day after picking. to preserve its sweetness, the freshly picked corn is immersed in boiling water fir a few minutes, and then cooled. which statement most likely explains why the boiled corn kernels remain sweet.

activated the enzyme that converts amino acids to sugar.

Experiments revealed the following information about a certain molecule: — It can be broken down into amino acids. — It can break down proteins into amino acids. — It is found in high concentrations in the small intestine of humans. This molecule is most likely

an enzyme

In living cells, chemical processes, such as synthesis, all require the action of

biological catalysts

plants such as Venus flytrap produce chemical compounds that break down insects into substances that are usable by the plant. the chemical compounds that break down the insects are most likely.

biological catalysts

which characteristics allows enzymes to function in a specific way?

each enzyme has a characteristic shape

Lipase, maltase, and protease are members of a group of catalysts known as>

enzymes

many disorders are due to the inability of an individual to break down a particular chemical. sometimes these disorders can be treated by giving the affected individual the appropriate.

enzymes

a fully functioning enzyme molecule is arranged in a complex three-dimensional shape. this shape determines the

rate at which the enzyme breaks down during a reaction it regulates

fruits and vegetables exposed to air begin to brown because of a chemical reaction in their cells. this may result in these foods being thrown out. some people have found that adding lemon juice (citric acid) to apple slices keeps them from turning brown. the prevention of browning is likely the result of

slowing the rate of enzyme action

enzyme molecules are produced by the life function known as

synthesis

which statement is most likely correct regarding soil bacteria that inhabit the polar regions of earth

they contain enzymes that function at low temperatures.
