Metabolic Pathways
The totality of an organism's chemical reactions is called this
Metabolism
The capacity to cause change or do work
Energy
This type of reaction proceeds with a net release of energy ("energy outward")
Exergonic Reaction
A chemical agent called a catalyst, that speeds up reactions in living systems, without being consumed by the reaction is called _______
an Enzyme
Which metal is found the most at the center of the Earth?
Iron
These metabolic pathways release energy by breaking down complex molecules
Catabolic Pathways
A concept known as ______ ______ can be used to determine the likelihood of reactions
free energy
This type of reaction absorbs free energy from its surroundings
Endergonic Reaction
The initial energy for starting a reaction
Activation Energy
What is the strongest muscle in the human body?
The jaw muscle (called the masseter muscle)
These metabolic pathways consume energy to build complicated molecules from simpler ones, for example, synthesizing proteins from amino acids
Anabolic Pathways
This word is used to describe a process that can occur on its own without an input of energy
Spontaneous
The hydrolysis of ATP is an example of a catabolic pathway. This breakdown produces inorganic phosphate and this molecule.
ADP
The reactant an enzyme acts on is referred to as this
Substrate
What was the first country to use paper money?
China
These are the two most important environmental factors that influence the activity of enzymes and affect the rate of a reaction
Temperature and pH
Energy can be transferred and transformed, but it cannot be created or destroyed.
First Law of Thermodynamics
The energy released by breakdown reactions (catabolism) in the cell is used to phosphorylate ADP, and thus regenerating this molecule
ATP
Only a restricted region of the enzyme molecule actually binds to the substrate, and is called this
Active Site
In which sport are the terms “stale fish” and “mule kick” used?
snowboarding
Compare and contrast anabolism and catabolism (give an example of both).
Catabolic pathways release energy by breaking down complex molecules into simpler compounds (cellular resp). Anabolic pathways that consume energy to build complicated molecules from simpler compounds (photosynthesis).
Every energy transfer or transformation increases the disorder (entropy) of the universe.
Second Law of Thermodynamics
This term is used to describe any case in which a protein's function at one site is affected by the binding of a regulatory molecule to a separate site
Allosteric Regulation
This type of inhibitor binds to an enzyme away from the active site, altering the conformation of the enzyme so that its active site no longer functions
Noncompetitive Inhibitor
How many seasons has Law and Order: Special Victims Unit had?
26 seasons
