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, and releasing oxygen as a byproduct.

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 are the main products of cellular respiration?

Back

The main products of cellular respiration are ATP (energy), 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 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 Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions in cellular respiration that takes place in the mitochondria, producing ATP, NADH, and FADH2.

Front

What is the electron transport chain?

Back

The electron transport chain is the final step of cellular respiration that occurs in the inner mitochondrial membrane, where electrons are transferred through a series of proteins, leading to the production of the majority of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that occurs when oxygen is not available, allowing cells to produce energy by converting glucose into lactic acid or ethanol and carbon dioxide.

Front

What types of cells perform cellular respiration?

Back

Both plant and animal cells perform cellular respiration to generate energy.

Front

What is the significance of ATP in cellular processes?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing the energy needed for various biological processes.
