Oriole IB ATP-Enzyme
vocab 4 energy ATP enzymes
Term | Definition |
---|---|
ACTIVATION | type of energy needed to start any chemical reaction |
ACTIVE SITE | the part of an enzyme that actually 'fits' the substance it works on |
CELLS | the smallest living parts of any living organism |
COENZYMES | organic molecules that can be used to change enzymes' shapes to make them work better |
DIFFUSION | the random movement of particles from higher to lower concentrations |
ENZYMES | molecules made of protein that are used to speed up chemical reactions in living cells |
EXERGONIC | chemical reactions that give off energy - an example would be a burning candle |
GLYCOLYSIS | energy needed to remake ATP from ADP comes from this process of breaking apart sugars |
HYDROLYSIS | process needs water to remove a phosphate from ATP in order to release energy |
KINETIC | also called the 'energy of motion', this is used by cells when they do work |
LYSOSOMES | organelles that break down food using powerful enzymes |
MULTICELLULAR | any organism that is composed of more than one cell is called this |
NITROGEN | element that is found in adenine, but not in ribose or phosphoric acid |
NUCLEUS | contains the genetic material (DNA) of a cell and controls all its functions |
PHOSPHORIC ACIDS | most of the stored energy in an ATP is found between these molecules |
POTENTIAL | type of energy that is stored in the high-energy bonds of ATP |
RIBOSE | the five-carbon sugar that is found in an ATP molecule |
RIBOSOMES | these organelles are necessary for producing the proteins that make up enzymes |
SUBSTRATE | the substance that an enzyme's shape attaches to (like a key fits in a lock) |
WATER | cytoplasm is made mostly of this; it's also given off during dehydration synthesis reactions |
ENDERGONIC | reactions that take in more energy than they give off - an example would be an cold pack you would put on a sprained ankle |
