Photosynthesis and Cellular Respiration Review

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 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 main purpose of photosynthesis?

Back

The main purpose of photosynthesis is to produce glucose, which serves as food for plants and as a source of energy for other organisms.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to convert the energy stored in glucose into ATP, which is used by cells for various functions.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What are the three main stages of cellular respiration?

Back

The three main stages of cellular respiration are glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain.

Front

What is glycolysis?

Back

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

Front

What is the citric acid cycle?

Back

The citric acid cycle, also known as the Krebs cycle, is the second stage of cellular respiration that occurs in the mitochondria, where pyruvate is further broken down, releasing carbon dioxide and transferring energy to electron carriers.

Front

What is the electron transport chain?

Back

The electron transport chain is the final stage of cellular respiration that occurs in the inner mitochondrial membrane, where electrons are transferred through a series of proteins, generating a large amount of ATP.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
