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
