  • Front
  • Back
gamete
a sex cell--a sperm in the male parent and an egg in the female parent.
organ
a group of different tissues that work togethr to carry out a particular function; the stomach is an example.
aerobic respiration
cellular respiration that uses oxygen, sequentially releasing energy and storing it in ATP.
tissues
in multicellular organisms, a specialized group of cells with the same basic structure that perform the same function.
polysaccharide
the most complex carbohydrate-such as cellulose,glycogen, or starch-which is formed by long chains of monosaccharides.
ATP
adenosine triphosphate; energy carrying molecule, which, when hydrolyzed to ADP and ingorganic phosphate, releases free energy.
eukaryote
cell containing a nuclear membrane and a membrane-bound nucleus: includes the vast majority of living organsims (for example, plants, animals, protists, and fungi).
acid
solution with a higher concentration of hydrogen ions than hydroxide ions; solutions with a pH below 7.
enzyme
reusable protein that lowers the required activation energy and allows reactions to happen at the normal temperatures of cells.
endergonic
chemical reaction requiring free energy in addition to enzymes and activation energy.
symbiosis
living together of two dissimilar organisms for their mutual benefit.
base
solution with a higher concentration of hydroxide ions than hydrogen ions; solutions wiht a pH above 7.
anaerobic
processes that occu in the absence of oxygen (for example, lactic acid fermentation and alcoholic fermentation).
carbohydrate
organic compound containing carbon, hydrogen, and oxygen; provides sources of energy for life processes.
amino acid
simple compound that is the building block of proteins.
prokaryote
cell that lacks a membrane-bound nucleus and membrane-bound organelles. Bacteria are examples.
polypeptide
many amino acids bonded together.
activation energy
minimum amount of energy needed to initiate a chemical reaction.
coenzyme
nonprotein, reusable helper molecule that helps enzymes activate chemical reactions.
exergonic
chemical reaction that releases free energy.
