Lecture 4 Flashcards
Metabolism of cells
sum of chemical reactions in an organism
metabolism
provides energy and building blocks for building activties in a cell
catabolism
equivilant to degradation or breakdown
catabolism
mostly exorgenic reactions
catabolism
uses energy to build larger molecules through catabolism
anabolism
equivelant to biosynthesis or condensation
anabolism
what is the universal energy currency of the cell
ATP
Biological catalyst
enzyme
true or false: most enzymes are proteins
true
Accelerate greatly the rate of chemical reactions and thus, allow an specific reaction to occur in cellular conditions
enzymes
factors which influence enzyme activity
temperature, pH, substrate concentration, inhibitors
what does NAD+ allow enzymes to do?
transfer electrons
The breakdown of glucose in the presence of oxygen to release energy. A sequence of 4 metabolic pathways
aeroboic respiration
The oxidation in the cytoplasm of glucose to pyruvic acid (pyruvate) produces ATP and NADH
glycolysis
A series of carrier protein complexes that are, in turn, reduced and oxidized as electrons are passed down the chain
