Cell Energy- Practice Test

Front

What is photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

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 the role of chlorophyll in photosynthesis?

Back

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

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and must consume other organisms for energy.

Front

What is an autotroph?

Back

An autotroph is an organism that can produce its own food from inorganic substances, typically through photosynthesis or chemosynthesis.

Front

What are the inputs (reactants) of photosynthesis?

Back

The inputs of photosynthesis are carbon dioxide and water.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is released into the atmosphere, which is essential for the survival of aerobic organisms.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can become denatured, losing their shape and functionality, which decreases the rate of biochemical reactions.

Front

What is the hydrophobic part of a phospholipid?

Back

The hydrophobic part of a phospholipid is the tails, which repel water.
