Front

What is the primary function of Cellular Respiration?

Back

To convert biochemical energy from nutrients into ATP, and release waste products.

Front

What are the main stages of Cellular Respiration?

Back

Glycolysis, Krebs Cycle (Citric Acid Cycle), and Electron Transport Chain.

Front

What is the role of NADH in Cellular Respiration?

Back

NADH acts as an electron carrier, transporting electrons to the electron transport chain.

Front

What is the significance of the proton (H+) gradient in Cellular Respiration?

Back

It drives ATP synthesis through ATP synthase during oxidative phosphorylation.

Front

What is the main product of the Krebs Cycle?

Back

Carbon dioxide (CO2), ATP, NADH, and FADH2.

Front

What is the role of oxygen in Cellular Respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, forming water.

Front

What is photosynthesis?

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin Cycle (light-independent reactions).

Front

What is the function of Rubisco in photosynthesis?

Back

Rubisco catalyzes the first step of carbon fixation, combining CO2 with ribulose bisphosphate (RuBP).

Front

What is produced during the light-dependent reactions of photosynthesis?

Back

ATP, NADPH, and oxygen.
