Introduction 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.
exergonic reaction
A spontaneous chemical reaction in which there is a net release of free energy.
Macromolecules
A very large organic molecule composed of many smaller molecules
Energy I used to combine amino acids building blocks in order to build a large protein, what type of reaction is this
Anabolic reaction
What is thI relationship between anabolism and catabolism
Anabolism builds molecules using energy produced during catabolism
Catabolic pathway
is the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions.
Catabolism
the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy; destructive metabolism.
Metabolism
the chemical processes that occur within a living organism in order to maintain life.
Anabolism
the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy
What best describes the proper terms to metabolically describe glucongenesis
It is an anabolic process with endergonic reactions that require an input of energy
A+B+C+energy€ ABC
It is an anabolic reaction
What is true of catabolism
It is the breakdown of larder molecules into smaller ones
Which of the following best defines metabolism?
The complete set of reactions carried out by a cell
AB€A+B+energy
Catabolic reaction
During glycolysis, the molecule glucose is broken down into pyruvate, what type of reaction is this ?
Catabolic reaction
Enzymes
Catalysts for chemical reactions in living things
Photosynthesis
Conversion of light energy from the sun into chemical energy.
During the Calvin cycle of photosynthesis, a plant cell uses carbon dioxide to synthesize large carbohydrates, what is true about this reaction
Energy is consumed
Why do we, as living organisms, need to consume food
Food is broken down by catabolic pathways and converted to ATP, which is then used to fuel anabolic pathways
What answer includes the proper terms to metabolically describe the process of digesting lactose
It is a catabolic process with an exergonic reaction the requires an output of energy
What best describes someone with a "slow" metabolism
Low rate of catabolism
cellular respiration
Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
metabolic pathway
a sequence of chemical reactions undergone by a compound or class of compounds in a living organism.
Anabolic pathway
are those that require energy to synthesize larger molecules
