Unit 5 Cellular Energy Flashcard

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells, used in various cellular processes.

Front

What is glycolysis?

Back

Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm, breaking down glucose into pyruvate and producing ATP.

Front

What is the role of glucose in cellular respiration?

Back

Glucose is a primary energy source for cells, which is broken down during cellular respiration to produce ATP.

Front

Where does photosynthesis occur?

Back

Photosynthesis occurs in the chloroplasts of plant cells, where sunlight is converted into chemical energy.

Front

What is the original source of energy for photosynthesis?

Back

The original source of energy for photosynthesis is sunlight.

Front

What is the Kreb's cycle?

Back

The Kreb's 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 is the electron transport chain?

Back

The electron transport chain is the final stage of cellular respiration, occurring in the inner mitochondrial membrane, where ATP is produced using electrons from NADH and FADH2.

Front

What is the difference between ATP and ADP?

Back

ATP (Adenosine Triphosphate) has three phosphate groups, while ADP (Adenosine Diphosphate) has two. ATP is the energy currency of the cell, and ADP is formed when ATP loses a phosphate group.

Front

What is the significance of oxygen in cellular respiration?

Back

Oxygen is the final electron acceptor in the electron transport chain, allowing for the production of ATP and water.

Front

What is the process of 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.
