Front

What is the dependent variable in an experiment?

Back

The dependent variable is the variable that is measured or tested in an experiment, which is affected by changes in the independent variable.

Front

What do enzymes do in chemical reactions?

Back

Enzymes decrease the activation energy of the reaction, making it easier for the reaction to occur.

Front

Where are proteins synthesized in a cell?

Back

Proteins are made in the ribosomes.

Front

What are cells?

Back

Cells are the smallest units of life that grow, reproduce, respond to stimuli, and use energy.

Front

Which enzyme is most efficient in a basic solution?

Back

Enzyme B is most efficient in a basic solution.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA.

Front

Define activation energy.

Back

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

Front

What is the function of the Golgi body?

Back

The Golgi body modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is the one that is changed or controlled in an experiment, while the dependent variable is the one that is measured.

Front

What is the significance of enzymes in biological reactions?

Back

Enzymes are crucial for speeding up biological reactions and allowing them to occur at the temperatures and conditions present in living organisms.
