Biology EOC Review 1

Front

What happens to the shape of an enzyme at high temperatures?

Back

The shape of the enzyme changes, which can decrease the rate of biochemical reactions.

Front

What is the primary function of the Paramecium's cilia?

Back

The cilia help the Paramecium move and feed.

Front

What is the role of ATP in cellular processes?

Back

ATP stores energy that can be used for various cellular activities.

Front

What type of macromolecule does salivary amylase break down?

Back

Salivary amylase breaks down starches, which are carbohydrates.

Front

What is the main product of the Calvin Cycle?

Back

The Calvin Cycle produces sugar from carbon dioxide (CO2).

Front

Define enzyme-substrate complex.

Back

An enzyme-substrate complex is formed when an enzyme binds to its specific substrate, facilitating a biochemical reaction.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How do temperature changes affect enzyme activity?

Back

Increased temperatures can denature enzymes, altering their shape and reducing their activity.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs consume other organisms for energy.

Front

What is the significance of the enzyme's active site?

Back

The active site is the region of the enzyme where substrate molecules bind and undergo a chemical reaction.
