something Flashcards
what are the two laws of thermodynamics?
1-energy cannot be created or destroyed(tranformed)
2-closed energy(nothing coming in or out) will increase is entropy(disorder) over time due to energy transformation
what are the two forms of energy?
potential energy and kinetic energy
define potential energy
store energy within system (function of order) bricks to wall analogy
define kinetic enegry
energy in process of doing work
order and potential energy?
AB —— A+B
AB has more order and more potential energy
A+B has less order less potential energy
2 ways to get energetic reaction started
1- increase temperature
2-lower activation energy with catalyst(enzyme)
define cofactors
inorganic compound required to bind to enzyme to activate site
define coenzyme
organic compound required to bond to enzyme to activate site
how to get
C+D ———CD
need energy and enzyme
define cellular respiration (aerobic)
breakdown of organic molecules into CO2 and H2O, releasing their energy +using energy to make energy carrying molecule called adenosine triphosphate(ATP)
define phosphorication
adding phosphate to something
4 processes in cell respiration
glycolysis, pyruvatcoxidation, kreb cycle/citric acid cycle, oxidation phosphorylation
what 5 things should you know about cell respiration proccesses?
- where it occurs
- what it starts with
- what you should get out of it(product)
- function of named molecules
- overall picture (making ATP)
define glycolysis
occurs in cytoplasm. breaking down sugar.
define nicotinemide adeninic dinuchotide and should know questions
bonds to H to get NADH which is a high energy elctron carrier. show know
1. occurs in cytoplasm
2. starts with 2 ADP, 2NAD+, 2Pi
3. get 2 pyruvate, 2ATP,2NADH
4. function high energy
