The cell’s capacity to aquire energy and use it to build, degrade, store, and release substances in controlled ways.
capacity for work
the measure of how much and how far a concentrated form of energy has beed dispersed after an energy change
Tell why we, as organized individual organisms, do not
violate the second law of thermodynamics.
The collective strength of chemical bonds resists the spontaneious direction of energy flow.
Distinguish between potential and kinetic energy.
Potential-a capacity for work because of something’s location and the arrangement of its parts.

Kinetic-energy of motion
Describe the structure of ATP.
5 carbon sugar, adenine base, 3 prosphate groups
Explain how ATP functions in the cell.
ATP fuctions as the cell’s energy currency.
Define the term "phosphorylation
Any phosphate group transfer
Diagram and describe the ATP - ADP cycle
ATP releases a phosphate group resulting in ADP. ADP becomes ATP by binding to an inorganic phosphate, or a phosphate group that was cleaved from another molecule
Define the term "activation energy."
Amount of energy required to get the reaction going on its own
Diagram and explain the induced fit model of enzyme function
An enzyme restrains a substrate that almost fits into its active site, and stretches the substrate until it fits
Describe the nature of an "active site."
Pocket or crevice where a substrate binds and is reacted upon
Feedback inhibition as a control of metabolic pathways
Allosteric site inclusion, where molecules in high concentration bind with sites and slow reactions. When substrates are in low concentration, the active site is unbound, increasing synthesis rates.
5.function and value of coenzymes
metal ions or coenzymes shift electron configurations in substrates.
What is the difference between exergonic and endergonic reactions? Give an example of each. What is the significance of each type of reaction
Anabolic (endergonic), protien construction, catabolic (exergonic), glycolosis
State the first law of thermodynamics
Energy cannot be created or destroyed
State the second law of thermodynamics
Energy flows from an area of greater to lesser concentration
