What is the Electron Transport Chain?

Back

The Electron Transport Chain (ETC) is the final stage of cellular respiration, occurring in the inner mitochondrial membrane, where electrons are transferred through a series of proteins, leading to the production of ATP and water.

Front

What gas do plants release during photosynthesis?

Back

Plants release oxygen as a waste product of photosynthesis.

Front

What is Pyruvate?

Back

Pyruvate is a key intermediate in cellular respiration, produced from glucose during glycolysis, and can be further processed in the Krebs Cycle.

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the Citric Acid Cycle, is the second step of cellular respiration that takes place in the mitochondria, where acetyl-CoA is oxidized to produce ATP, NADH, and FADH2.

Front

What is chlorophyll?

Back

Chlorophyll is the main light-absorbing pigment found in plant leaves, essential for photosynthesis as it captures light energy.

Front

What is the role of glycolysis in cellular respiration?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into two molecules of pyruvate, producing a small amount of ATP and NADH.

Front

What is the main purpose of photosynthesis?

Back

The main purpose of photosynthesis is to convert light energy into chemical energy stored in glucose, while releasing oxygen as a byproduct.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is the significance of ATP in cellular processes?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various biochemical reactions.

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.
