Biomolecules & Enzyme Regents Review

Front

What type of organic molecule is responsible for reducing water loss in plants due to its waxy coating?

Back

Lipid

Front

How many calories are typically listed on a food label?

Back

240

Front

What determines the shape of a protein?

Back

The arrangement of amino acids in the protein.

Front

What are the two main factors that can denature an enzyme?

Back

pH and temperature.

Front

What happens to enzyme activity at high temperatures?

Back

Enzyme activity declines due to denaturation.

Front

What is the primary function of lipids in biological systems?

Back

Energy storage, insulation, and forming cell membranes.

Front

Define denaturation in the context of enzymes.

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like temperature or pH.

Front

What is the role of amino acids in protein structure?

Back

Amino acids are the building blocks of proteins and determine their structure and function.

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to denaturation and reduced activity.

Front

What is the significance of temperature in enzyme-catalyzed reactions?

Back

Temperature affects the rate of enzyme activity; too high or too low can lead to denaturation.
