Aerobic cellular respiration Flashcards
what is the purpose of cellular respiration
to use energy stored as glucose to create ATP, cells require energy to survive
how does atp provide energy
energy stored in the bonds of glucpse needs to be transfered to ADP molecules so it can form ATP before it can be used by cells
what kind of reaction is cellular respiration
catabolic and exergonic, heat energy iis also realesed
how is glucose stored in plants
glucose (monosaccaride) is stored as starch (polysaccharide)
how is glucose stored in animals
glucose (monosaccaride) is stored as glycogen (polysaccaride)
before cellular respiration what occurs
the polysaccharides must be broken down into glucose by enzymes
ADP stands for
adenosine diphophate
How long does ATP stay as ATP
is a temporary molecule, so is believed to average 60 secs from its production until it realeases its energy for use by the cell
aerobic cellular respiration equation worded
glucose + oxygen = Carbon dioxie + water + 30/32 ATP
structure of the mitochondria
small organelles found scattered around the cytosol of eukaryotic cells, has a smooth outer memebrane and highly folded inner memembrane (cristae) and the matrix, they contain their own dna in circular chromosomes (mrDNA)
cristae
the folds created by the inner membrane
matrix
the inner space of the inner membrane, it consists of protein rich fluid
mitochondria evidence of endosymbiotic theory
close to size of bacterium, replicattes via binary fission, is double memebrane bound
3 stages of aerobic cellular respiration
glycolysis, krebs cycle, electron transport chain
where does glycolysis occur
in the cytosol
