Enzymes

Front

Enzymes increase the rate of chemical reactions in cells by:

Back

reducing the activation energy.

Front

Substance acted upon by an enzyme?

Back

Substrate

Front

In the diagram, letter A is:

Back

enzyme-substrate complex

Front

Optimal temperature for the enzyme based on the graph?

Back

30°C

Front

Effect of enzyme denaturation on reaction rate?

Back

Decrease in reaction rate

Front

Which of the following would NOT denature an enzyme? HIGH temp, LOW pH, HIGH pH, LOW temp.

Back

LOW temp.

Front

Experiment with human small intestine enzyme saturated with substrate. Most effective way to speed up product formation:

Back

Add more enzyme.

Front

Enzyme-controlled reaction results:

Back

Most active at pH 4.6

Front

Rate of an enzyme-catalyzed reaction can be determined by:

Back

The rate of substrate used up.

Front

Enzymes can build or break down a substrate.
