CELLULAR RESPIRATION

Front

What is cellular respiration?

Back

Cellular respiration is a biochemical process in which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

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 glycolysis?

Back

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

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the Citric Acid Cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient for ATP synthesis.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, resulting in byproducts like lactic acid or ethanol.

Front

What is the significance of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the electron transport chain, playing a crucial role in ATP production.
