the amount of energy needed to raise the temperature of 1 gram of water 1 degree celcius


the process in which a glucose molecule is split in half

pyruvic acid, a 3 carbon compound

what is the product of glycolysis

cellular respiration

process that releases energy by breaking down glucose and other food molecules in the presence of oxygen


(nicotinamide adenine dinucleotide) an electron carrier molecule that helps to pass energy from glucose to other pathways in the cell


process by which cells release energy in the absence of oxygen


process that doesn't require oxygen


process that requires energy

kreb cycle

2nd stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions

electron transport chain(ETC)

a series of proteins in which the high energy electrons from the kreb cycle are used to convert ADP to ATP


where the final stage of cellular respiration takes place


where does photosynthesis takes place

to make ATP

what is the purpose of cellular respiration

make glucose

what is the purpose of photosynthesis


first step in cellular respiration


the process of turning 1 glucose into 2 pyretic acid

cytoplasm, outside of the mitochondria

where does glycolysis take place


what is the electron acceptor in glycolysis


what does NAD+ turn into in glycolysis

break down food into ATP

what is the purpose of cellular respiration


what is the equation for cellular respiration

2 pyruvic acid

what does glycolysis turn 1 glucose into

energy investment phase

phase in glycolysis that involves putting in 2 ATP to get the reaction started

energy yielding phase

phase in glycolysis where 2 PGAL are turned into 2 pyruvic acid, another 3 carbon molecule and releases 4ATP with net gain of 2 ATP and 2 NAD+ turned into 2 NADH

Hans Kreb

who is the kreb cycle named after

matrix of mitochondria

where does the kreb cycle take place

citric acid cycle

what is another name for the krebs cycle

make more electron carriers to make ATP in the ETC

what is the purose of the krebs cycle

4co2, 6 NADH, 2 FADH2 and 2ATP

what does krebs cycle result in

alcohol and lactic acid

what are the 2 main types of fermentation


what is the last electron acceptor of the ETC


where does lactic acid fermentation take place during rapid exercise?


if oxygen is present, what do kreb cycle and electron transport chain follow

citric acid is the first product

why is the kreb cycle known as citric acid cycle?
