The important molecules of cellular respiration are :- A) Glucose, B) Oxygen, C) Carbon dioxide, D)ATP, E) NAD, F)FAD.
The important molecules involved in cellular respiration include:
A) Glucose: This is the sugar molecule that is broken down for energy in cellular respiration.
B) Oxygen: This is needed for the electron transport chain, which is the last step of cellular respiration and where most of the ATP is produced.
C) Carbon dioxide: This is a waste product of cellular respiration.
D) ATP (adenosine triphosphate): This is the energy currency of the cell. It is made in cellular respiration and used to power all of the cell's activities.
E) NAD (nicotinamide adenine dinucleotide): This molecule carries electrons from one step of cellular respiration to another.
F) FAD (flavin adenine dinucleotide): This molecule is similar to NAD and also carries electrons in cellular respiration.
The Krebs cycle is a series of chemical reactions that takes place in the mitochondria of cells. It breaks down pyruvate, which is a product of glycolysis, into carbon dioxide and ATP. The Krebs cycle also produces NADH and FADH2, which are used in the electron transport chain to make ATP.
Here are some other important molecules involved in cellular respiration:
Pyruvate: This is a product of glycolysis that is used in the Krebs cycle.
Acetyl CoA: This is a molecule that is made from pyruvate and enters the Krebs cycle.
Citric acid: This is a molecule that is made in the Krebs cycle.
Oxaloacetate: This is a molecule that is needed to start the Krebs cycle.
