Photosynthesis and Cellular Respiration

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 obtain energy from glucose, breaking it down in the presence of oxygen to produce carbon dioxide, water, and energy (ATP).

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose (sugar), which serves as an energy source for plants.

Front

What are the reactants needed for photosynthesis?

Back

The reactants needed for photosynthesis are carbon dioxide, water, and light energy.

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.

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 are thylakoids?

Back

Thylakoids are membrane-bound compartments inside chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

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 photosynthesis.

Front

What is the significance of the Grana in chloroplasts?

Back

Grana are stacks of thylakoids in chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is the equation for photosynthesis?

Back

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