Biology 1 EOC Practice Questions

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose, using carbon dioxide and water.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is ATP and its significance in cellular processes?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are glycolysis, the Krebs cycle, and the electron transport chain.

Front

How do plants and algae relate to each other in terms of evolution?

Back

Modern land plants are believed to have evolved from green algae, sharing similarities in cell structure and chlorophyll.

Front

What is the function of fats in the human body?

Back

Fats provide insulation, store energy, and cushion vital organs.

Front

What is the function of proteins in the human body?

Back

Proteins are essential for growth, repair, and the regulation of body processes, including muscle contraction.

Front

What is the significance of carbon in biological molecules?

Back

Carbon is the backbone of many biological molecules, forming the basis for carbohydrates, proteins, lipids, and nucleic acids.

Front

What is glycolysis?

Back

Glycolysis is the first step in cellular respiration where glucose is broken down into pyruvate, producing a small amount of ATP.
