Photosynthesis and Cellular Respiration

Front

What is the primary function of the mitochondria in cellular respiration?

Back

The mitochondria are responsible for producing ATP through the Krebs cycle and electron transport chain.

Front

What are the three main products of cellular respiration?

Back

Carbon dioxide, water, and usable energy (ATP).

Front

What is a producer in the context of photosynthesis?

Back

A producer is an organism, such as a house plant, that can make its own food through photosynthesis.

Front

Why is carbon considered an essential element for living organisms?

Back

Carbon is a fundamental building block of life, forming the backbone of organic molecules.

Front

What role does NADPH play in photosynthesis?

Back

NADPH is a source of energy and reducing power for the light-independent reactions (Calvin cycle) of photosynthesis.

Front

What are the light-dependent reactions of photosynthesis?

Back

The light-dependent reactions convert solar energy into chemical energy in the form of ATP and NADPH.

Front

What is the significance of the Krebs cycle in cellular respiration?

Back

The Krebs cycle generates electron carriers (NADH and FADH2) that are used in the electron transport chain to produce ATP.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis and release oxygen, playing a crucial role in the carbon cycle.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
