Throwback/Flashback Enzyme mini lesson

By Laura Rodriguez

The substrate binds to the enzyme at the active site - the shape matches - induced fit!

Enzymes are specific to substrates

Enzymes speed up chemical reactions by lowering the activation energy required to start the reaction

Enzymes are catalysts

Changes in pH, temperature, salinity, will slow down the action of the enzyme

Enzymes & the environment

Enzymes work in specific environmental ranges

Multiple Choice

An enzyme speeds up a reaction by

lowering the activation energy.

raising the activation energy.

releasing energy.

absorbing energy.

Multiple Choice

What happens when enzymes are heated to a high temperature?

The enzymes die.

The shape of the enzyme are changed and it denatures

The enzymes' amino acid sequence changes.

The enzymes remain the same

Multiple Choice

Each enzyme only has 1 substrate that will fit its active site. What is this called?

reusablility

denaturation

specificity

fragility

Multiple Choice

Which of the following conclusions can be drawn from this graph?

The optimum pH of the enzyme is 6.6.

The optimum pH of the enzyme is 5.8

The enzyme’s activity increases as pH increases 5.0 to 9.0

The enzyme’s activity is greater around pH of 8.0 .

Multiple Choice

Multiple Choice

Enzymes are composed of which of the following monomers?

amino acids
