Organic Catalysts

Chemicals that help chemical reactions occur at faster rates in living organisms are known as

Simple Sugars

The building blocks for this molecule are

Amino Acids

The inability of an organism to produce certain proteins can occur when an organism is lacking an enzyme needed to combine

Temperature of the water

A change in the rate of enzyme action in aquatic invertebrates would most directly result from a change in the

Shape of their molecules

A characteristic shared by all enzymes, hormones, and antibodies is that their function is determined by the

Specific type of molecule it interacts with during the reaction

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

Reactions that are controlled by catalysts

All chemical breakdown processes in cells directly involve

Synthesis of enzymes

In a heterotrophic organism substance A could be used directly for

Linked together to form proteins

In plants, simple sugars are least likely to be

Synthesis

In which process are simple materials chemically combined to form more complex materials?

Organic compounds

Proteins, starch, and DNA are similar in that they are all

Shapes of the molecules involved

The ability of an enzyme molecule to interact with specific molecules is most directly determined by the

Chymotrypsin

The activity of which enzyme decreases in both acidic and basic environments?

Enzymes

The chemicals present in the plants that break down the insects are most likely

In the bonds between atoms

The energy in this molecule is stored

Molecule C only

The enzyme will most likely affect reactions involving

Physical Shape

The function of a specific enzyme is most directly influenced by its

Both enzymes would exhibit some activity at pH 5

The most likely results of mixing both enzymes with their substrates in a single test tube is that

Dehydration synthesis

The reaction indicated by arrow E illustrates

Functions inside and outside of cells

The shape of the protein molecule directly determines its

The activity of an enzyme is affected by pH

What is the true statement about the relationship between pH and enzyme action?

It would be able to function because the pH of the environment is similar to that of the intestine

What will most likely happen to the action of an enzyme from a small intestine if it is placed in an environment similar to the environment in which enzymes C functions best?

The dipeptide would digest slower or not at all

What would happen if a temperature changed caused the shape of the active site to be altered?
