Which statement best describes enzymes?

Every enymes controls many different reactions

Temperature changes do not affect enzymes

The rate of the activity of an enzyme might change as the pH changes

Enzymes are produced from the building blocks of carbohydrates

increases, then decreases

remains the same

increases

decreases

Which list of molecules is arranged in order of decreasing size?

oxygen, glucose, sucrose, starch

oxygen, starch, glucose, sucrose

starch, glucose, sucrose, oxygen

sucrose, oxygen, starch, glucose

1

Cellulose is formed from glucose molecules by a process known as

cellular respiration

photosynthesis

hydrolysis

dehydration synthesis

1

An excess of enzyme X was present, resulting in a decrease in the production of substance B

Excess energy for step 2 prevented the conversion of substance B to substance C

A mutation occurred causing the change in the ability of the cell to use substance C

Nuclear DNA was altered resulting in the cell being unable to make enzyme Y

1

Which condition is necessary for enzymes and hormones to function properly in the human body?

These chenicals must be able to replicate

Body pH must be above 10

Body Temperature must be above 40 C

These chemicals must have a specific shape
