Introduction to Cellular Energy and Photosynthesis

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 primary function of ATP?

Back

ATP (Adenosine triphosphate) serves as the main energy currency of the cell, providing energy for various cellular processes.

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 oxygen and glucose (sugar).

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 the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the Second Law of Thermodynamics?

Back

The Second Law of Thermodynamics states that in any energy transfer, the total entropy (disorder) of a closed system will always increase over time.

Front

What is metabolism?

Back

Metabolism refers to all the chemical reactions that occur within a living organism to maintain life, including both anabolic (building up) and catabolic (breaking down) processes.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen and produces less energy.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis, providing electrons and protons needed for the formation of glucose and releasing oxygen as a byproduct.
