Intro to Metabolism

ADP

(Adenosine Diphosphate) The compound that remains when a phosphate group is removed from ATP, releasing energy

ATP

(adenosine triphosphate) main energy source that cells use for most of their work

endergonic reaction

A non-spontaneous chemical reaction in which free energy is absorbed from the surroundings.

A+B+C+energy-ABC

Anabolic reaction

Energy is used to combine amino acid building blocks in order to build a large protein. What type of reaction is this

Anabolic reaction

What is the relationship between anabolism and catabolism

Anabolism builds molecules using the energy produced during catabolism

Metabolism

the chemical processes that occur within a living organism in order to maintain life.

Cellular respiration

the process by which cells use oxygen to produce energy from food

Which of the following is true of catabolism

It is the breakdown of larger molecules into smaller ones

Which of the following defines metabolism

The complete set of reactions carried out by a cell

metabolic pathway

Begins with a specific molecule, which is then altered in a series of defined steps, resulting in a certain product.

AB -> A+B+energy

Catabolic reaction

During glycolysis the molecule glucose is broken down into pyruvate

Catabolic reaction

exergonic reaction

Chemical reaction that releases energy; opposite of endergonic reaction.

Anabolism

Constructive metabolism; the process of building up larger molecules from smaller ones.

During the Calvin cycle of photosynthesis a plant cell uses carbon dioxide to synthesize large carbohydrates

Energy is consumed

Why do you as a living organism need to continually consume food

Food is broken down by catabolic pathways and converted to ATP which is then used to fuel anabolic pathways

Which of the following include the proper term- to metabolically describe the process of digesting lactose

It is a catabolic process with an endergonic reaction that requires an output of energy

Which of the following contains the proper terms to metabolically describe gluconeogenesis

It is an anabolic process with endergonic reaction that require and input of energy

Which of the following answer choices best describes someone with a slow metabolism

Low rate of metabolism

Photosynthesis

Plants use the sun's energy to convert water and carbon dioxide into sugars

Marcomolecules

Protein, Nucleic Acid, Carbohydrates, and Lipids.

Enzymes

Proteins that speed up chemical reactions

anabolic pathway

a metabolic pathway that consumes energy to synthesize a complex molecule from simpler molecules

catabolic pathway

a metabolic pathway that releases energy by breaking down complex molecules to simpler molecules

Catabolism

breaking down
