Front

What is energy coupling?

Back

Energy coupling is the process where an endergonic reaction (which requires energy) is fueled by an exergonic reaction (which releases energy).

Front

What is glycolysis?

Back

Glycolysis is the metabolic process that breaks down glucose to form ATP, NADH, and pyruvate, releasing energy in the process.

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is its unique sequence of amino acids, which is unaffected by denaturation.

Front

What causes denaturation of enzymes?

Back

Denaturation of enzymes can be caused by extreme increases in temperature and changes in pH, which disrupt the enzyme's structure.

Front

What is the difference between competitive and noncompetitive inhibitors?

Back

Competitive inhibitors bind to the active site of an enzyme, while noncompetitive inhibitors bind to a different site, altering the enzyme's function.

Front

What is the second law of thermodynamics?

Back

The second law of thermodynamics states that in any energy transfer, the total entropy of a closed system will always increase over time.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the metabolic pathway that uses energy released by the oxidation of nutrients to produce ATP.

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is denaturation?

Back

Denaturation is the process in which proteins lose their structure and function due to external stressors like heat or pH changes.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.
