Enzymes & Energy

Front

What is an example of an exergonic reaction?

Back

Cellular Respiration

Front

What are the two most common ways in which enzymes become denatured?

Back

Changes in temperature and pH

Front

What effect does adding more substrate have on the rate of reaction?

Back

It increases the rate of reaction.

Front

What is the optimum pH of the enzyme if a graph indicates a peak at pH 6.6?

Back

The optimum pH of the enzyme is 6.6.

Front

What type of energy is chemical energy classified as?

Back

Potential Energy

Front

Define enzymes in the context of biological reactions.

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in biological systems.

Front

What is the role of enzymes in metabolic pathways?

Back

Enzymes facilitate and regulate the biochemical reactions in metabolic pathways.

Front

How does temperature affect enzyme activity?

Back

Increased temperature generally increases enzyme activity up to a certain point, after which the enzyme may denature.

Front

What is the relationship between enzyme concentration and reaction rate?

Back

Increasing enzyme concentration typically increases the reaction rate, provided there is enough substrate.

Front

What is activation energy?

Back

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