Understanding Cellular Respiration

Front

What is the first step of glycolysis?

Back

Conversion of glucose to glucose-6-phosphate

Front

Which molecule is the final electron acceptor in the electron transport chain?

Back

Oxygen

Front

How many ATP molecules are produced from one molecule of glucose during glycolysis?

Back

2

Front

What is the main purpose of the Krebs cycle?

Back

To produce NADH and FADH2 for the electron transport chain

Front

Product of anaerobic respiration in muscle cells?

Back

Lactic acid

Front

What is the role of NADH in cellular respiration?

Back

It carries electrons to the electron transport chain

Front

During which stage of cellular respiration is the majority of ATP produced?

Back

Electron Transport Chain

Front

Compare the efficiency of ATP production in aerobic vs anaerobic respiration.

Back

Aerobic respiration produces more ATP than anaerobic respiration.

Front

Which enzyme is responsible for the phosphorylation of glucose in glycolysis?

Back

Hexokinase

Front

Explain the role of FADH2 in the electron transport chain.

Back

It donates electrons at a lower energy level than NADH.
