Molecular Biology Review

Front

What substances act as catalysts for metabolism?

Back

Enzymes are biological catalysts that speed up metabolic reactions.

Front

What molecule stores energy, insulates, and is insoluble in water?

Back

Fats (lipids) are molecules that store energy, provide insulation, and are hydrophobic.

Front

What process produces the most ATP per molecule of glucose?

Back

Aerobic respiration is the process that generates the most ATP from glucose.

Front

What will most likely happen if the level of carbon dioxide available to a plant is reduced?

Back

The plant will produce less glucose due to reduced photosynthesis.

Front

What substance provides energy to the cell to carry out active transport?

Back

ATP (adenosine triphosphate) provides the energy for active transport.

Front

What is the primary function of enzymes in biological systems?

Back

Enzymes catalyze biochemical reactions, lowering the activation energy required.

Front

What is the role of lipids in the cell membrane?

Back

Lipids form the bilayer structure of cell membranes, providing barrier and fluidity.

Front

What is photosynthesis and where does it occur?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy, occurring in chloroplasts.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the significance of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, powering various biological functions.
