C1.2: Cell Respiration

Front

What is cell respiration?

Back

Cell respiration is the process by 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 ATP in cellular processes?

Back

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

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, resulting in the production of energy and byproducts like lactic acid or ethanol.

Front

How does exercise affect blood pH levels?

Back

During exercise, blood pH decreases due to the accumulation of lactic acid from anaerobic respiration.

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 are the products of glycolysis?

Back

The products of glycolysis are 2 pyruvate molecules, 2 ATP, and 2 NADH.

Front

What is the significance of the Krebs Cycle?

Back

The Krebs Cycle generates electron carriers (NADH and FADH2) and ATP, and releases carbon dioxide as a waste product.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a passive transport process that allows substances to cross membranes with the assistance of special proteins, without the use of ATP.

Front

What are the products of the hydrolysis of ATP?

Back

The hydrolysis of ATP produces ADP (adenosine diphosphate), inorganic phosphate, and energy.
