Chapter 7 Metabolism

What does ETS stand for?

Electron transport chain.

What is the product of catabolism of carbohydrate ?

-

What does the term anabolic mean?

- Anabolic reactions involve creating bonds to build larger products.

The catabolism of energy nutrients leads to the production of what?

-ATP

What does ATP stand for?

-Adenosine triphosphate.

What does energy fuel in the body?

-Anabolic reactions

What is the energy yielding pathway for Carbs?

-Carbohydrate to glucose to Pyruvate to Acetyl CoA to TCA cycle to electron transport chain to ATP/H2O

What does the term catabolic mean?

-Catabolic reactions involve breaking down larger compounds into smaller products.

What is the energy yielding pathway for fat?

-Fat to glycerol/Fatty acids to Pyruvate to Acetyl CoA to TCA cycle to electron transport chain to ATP/H2O

What are the three energy nutrients?

-Fats, proteins, carbohydrtes

What is the product of the catabolism of fats?

-Fatty acids

ATP is delivered through out the body as a what?

-Fuel source to all the cells to provide energy to drive all the catabolic reactions

Catabolism is also known as what?

-Oxiddation

What is the energy yielding pathway for proteins?

-Protein to amino acids to Pyruvate to Acetyl CoA to TCA cycle to electron transport chain to ATP/H2O

Anabolic and catabolic reactions result in what?

-Release of energy.

What is the TCA cycle?

-Series of metabolic reactions that break down molecules of acetyl CoA to carbon dioxide and hydrogen atoms.

The body "couples" an anabolic reaction with a catabolic reaction to do what?

-The energy from the breaking of one bond (the catabolic reaction) is used to form the bond in an anabolic reaction.

What is the electron transport chain?

-The final pathway in energy metabolism that transports electrons from hydrogen to oxygen and captures energy released in the bonds of ATP.

What is glycolysis?

-The metabolic breakdown of glucose to pyruvate.

What must the three energy nutrients do first to provide energy for anabolic reactions?

-They must be catabolized (broken down or oxidized.)

What does TCA stand for in the TCA cycle?

-Tricarboxylic Acid

what is the product of catabolism of protein ?

-amino acids, which are used as energy source

when does protein catabolism occur?

-under conditions of starvation, after glycogen stores have been depleted and fatty acids levels are low
