Front

Why does the rate of a biochemical reaction decrease at high temperatures?

Back

The shape of the enzyme changes.

Front

What is most likely the source of energy for the contractile vacuole process in protists?

Back

ATP

Front

Which structure is most likely affected when a chemical is added to the pond water in which the Paramecium lives, causing it to stop moving?

Back

1

Front

Which molecules are joined together to make proteins?

Back

amino acids

Front

This diagram shows a red blood cell in a beaker that contains a solution with a higher salt concentration than that inside the red blood cell. What will happen to the red blood cell in this environment?

Back

The red blood cell will shrink from losing water molecules.

Front

A student noticed that the freshwater plant, Elodea, produced bubbles when placed in direct light. What could the student most likely conclude?

Back

Bubbles of oxygen were produced as a result of photosynthesis.

Front

A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?

Back

They will shrink because water will move out of them.

Front

If energy is needed to move materials into or out of a cell, what is most likely occurring?

Back

active transport

Front

What is the best evidence that a cell is using active transport to move a substance across its cell membrane?

Back

ATP is being rapidly consumed near the cellular membrane.

Front

In a controlled experiment, a limited quantity of glucose was provided for cellular respiration. Researchers measured the quantity of reactants and products at the beginning of the experiment and again after 10 minutes. How will the quantities of glucose, oxygen, and carbon dioxide most likely change after 10 minutes have passed?

Back

glucose will decrease, oxygen will decrease, carbon dioxide will increase
