|
Energy |
The capacity to cause change |
|
|
kinetic energy |
Energy in motion |
|
|
potential energy |
stored energy. object has because of structure and location |
|
|
Chemical energy |
molecules store varying amounts of potential energy in the arrangement of their atoms. Organic compounds are relatively rich in chemical energy. The combustion of gasoline within a cars engine and the breakdown of glucose via cellular respiration with living cells are both examples of how the chemical energy stored in molecules can be converted to useful work. |
|
|
calorie |
amount of energy that raise the temp of 1 gram of water 1 degree c |
|
|
chemical energy |
is released by the breakdown of organic molecules during cellular respiration used to make APT. Consists one organic molecule adenosine with a tail of 3 phosphate groups |
|
|
metabolism |
total of all chemical reactions in a cell |
|
|
Enzymes |
proteins that speeds up chemical reactions without being consumed by the reaction |
|
|
Activation energy |
Energy that must be invested to start a reaction by activating the reactant and triggering a chemical reaction |
|
|
substrate |
certain reactant molecule |
|
|
Active site |
have shape and chemistry that fits the substrate molecule |
|
|
Induced fit |
interaction happens because of entry of a sub strate induces the enzyme to change shape slightly making the g It between substrate and active site fit snugger |
|
|
enzyme inhibitors |
substrate imposters that plug up action sites |
|
|
diffusion |
movement of molecules spreading out evenly into the available space |
|
|
passive transport |
diffusion of a substance across a membrane without the input of energy |
|
|
facilitated diffusion |
type of passive transport because it does not require the cell to expend energy |
|
|
osmosis |
the diffusion of water across a selectively permeable membrane |
|
|
hypersonic solution |
higher concentration of solute |
|
|
hypersonic solution |
lower concentration of solute |
|
|
isotonic solution |
equal concentration of solute |
