Front

Where on an enzyme does the substrate bind?

Back

active site

Front

Effect on free energy of doubling the amount of enzyme.

Back

No effect on free energy.

Front

Which structure is unaffected by denaturation?

Back

Primary

Front

Which environmental conditions can cause denaturation of the enzyme?

Back

extreme increase in temperature and pH changes

Front

Which of the following will increase the rate of the reaction? increase product, increase substrate, increase inhibitor, increase enzyme

Back

increase enzyme

Front

Why does an increase in temperature increase the rate of the reaction?

Back

Increase in temperature increases the speed/kinetic energy of particles.

Front

Describe the difference between competitive and noncompetitive inhibitors.

Back

Competitive inhibitors bind to the active site, while noncompetitive inhibitors bind to another site.

Front

In order to maintain order and power cellular processes,

Back

energy input must exceed energy loss

Front

What is the process of an endergonic reaction being fueled by an exergonic reaction called?

Back

energy coupling

Front

Where did photosynthesis first evolve?

Back

prokaryotic organisms
