Answers

Catabolism - CORRECT ANSWER✔✔-degradation of complex molecules
| | | | | | |



into smaller ones resulting in a release of stored energy; used by
| | | | | | | | | | | |



anabolic pathways |




anabolism - CORRECT ANSWER✔✔-synthesis of complex molecules that
| | | | | | |



requires input of energy
| | | |




ATP - CORRECT ANSWER✔✔-molecule with the most stored energy,
| | | | | | | | |



commonly used by reactions to continue
| | | | |




hydrolysis - CORRECT ANSWER✔✔-the ________________ of ATP
| | | | | | |



releases energy |




enzymes - CORRECT ANSWER✔✔-specific proteins that catalyze specific
| | | | | | | |



reactions


enzyme - CORRECT ANSWER✔✔-protein which contain an active site
| | | | | | | | |



which modifies a molecule called the substrate into a product
| | | | | | | | |

,substrate - CORRECT ANSWER✔✔-what binds to an enzyme to activate
| | | | | | | | |




competitive inhibition - CORRECT ANSWER✔✔-type of inhibition in
| | | | | | | |



which a structure similar to the substrate binds the active site of an
| | | | | | | | | | | | |



enzyme and prevents the reaction
| | | |




non-competitive inhibition - CORRECT ANSWER✔✔-type of inhibition in
| | | | | | | |



which a molecule binds elsewhere on the enzyme and changes the
| | | | | | | | | | |



conformation of the active site | | | |




feedback inhibition - CORRECT ANSWER✔✔-type of inhibition where a
| | | | | | | | |



pathway is inhibited due to high levels of a molecule often later in the
| | | | | | | | | | | | | |



pathway; like a thermostat
| | |




mitochondria and chloroplast - CORRECT ANSWER✔✔-two energy
| | | | | | |



forms that are mutual between plant and animal cells; both are power
| | | | | | | | | | | |



provider, membrane bound organelles which contained DNA and
| | | | | | | |



ribosomes


Endosymbiant theory - CORRECT ANSWER✔✔-theory which states that
| | | | | | | |



chloroplasts and mitochondira have evolved directly from bacteria that
| | | | | | | | |



were internalized into another prokaryotic cell
| | | | |




symbiosis - CORRECT ANSWER✔✔-means "living together"
| | | | |

, mutualism - CORRECT ANSWER✔✔-type of symbiosis where both
| | | | | | | |



parties benefit
|




comensalism - CORRECT ANSWER✔✔-symbiosis where one party
| | | | | | |



benefits with little to no effect on the other
| | | | | | | |




parasitism - CORRECT ANSWER✔✔-symbiosis where one party benefits
| | | | | | | |



at the expense of the other
| | | | |




cristae - CORRECT ANSWER✔✔-folds of the inner membrane of the

___________________ membrane, consisting of an inner and outer | | | | | | | |



membrane
