New cards
how many steps does glycloysis have
10
2
New cards
does each step of glycloysis have its own enzyme
yes
3
New cards
where does glycloysis take place
the cytoplasm
4
New cards
what are the first 5 steps of glycloysis
energy investment
5
New cards
what are the last 5 steps of glycloysis
energy payout
6
New cards
what are the end products of glycloysis
 2 atp, 2 nadh, and 2 pyruvic acids (222)
7
New cards
where does the krebs cycle and electron transport take place
the mitochondria
8
New cards
what is the first stage of cellular respiration
glycolysis
9
New cards
krebs cycle is also known as what
citric acid cycle
10
New cards
how many spins are in the krebs cycle
2 molecules for every pyruvic acid
11
New cards
end result of krebs cycle
2 atp, 6 co2, 8 nadh, 2 fadh2
12
New cards
what is a calorie
the amount of energy required to raise the temp of 1 gram of water by 1 degree Celsius
13
New cards
what is A calorie (food labels)
a kilo-calorie=1000 calories
14
New cards
cellurlar respiration=
glycloysis+ krebs cycle+ electron transport chain ( in the presence of oxygen which is areobic)
15
New cards
what is cellular respiration
the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
16
New cards
what is the formula for cellular respiration
6o2+c6h12o6→ 6co2 + 6h2o + energy
17
New cards
what is glycolysis
the process in which one molecule of glucose is broken into 3 carbon molecules (pyruvic acid)
18
New cards
for atp production, how many molecules are needed to start the reaction, and how many are made
2 ATP molescules are needed to start the reaction, 4 atp molecules are made, and their is a net gain of 2 ATP molecules
19
New cards
what is NAD+
nicotinamide adenine dinucleotide- electron carrier
20
New cards
NAD+ accepts a pair of high energy electrons and becomes what
NADH
21
New cards
NADH carries electrons to other what
pathways
22
New cards
oxidative respiration=
krebs cycle and electron transport chain
23
New cards
pyruvic acid is broken down into
co2 in a series of energy extracting reactions
24
New cards
during the krebs cycle, what is the first compound formed
citric acid
25
New cards
1 carbon from each pyruvic acid become
a molecule of co2 and is released
26
New cards
how many carbon atoms from pyruvic acid are joined to coenzyme A to make Acetyl coA
2
27
New cards
Acetyl coA combines with
a 4 carbon molecule to form citric acid
28
New cards
cotroc acid is borken into a
4 carbon molecule and co2 is released
29
New cards
electrons are transferred to energy carries, and how many carbon molecules start the cycle all over again
4
30
New cards
throughout the cycle, a pair of high energy electrons changes nad+ to what and fad to what
NAD+ to NADH and FAD to FADH2 (electron carrier)
31
New cards
electrons passed to ____ __and__ __ __are carried to the electron transport chain to convert__ ____to______
NADH and FADH, to convert ADP to ATP. this occurs in a series of carrier proteins at the inner membrane of the mitochondria
32
New cards
at the end of the electron transport chain, high energy electrons combine with __ __and__ _ to form what
combine with H+ ions and oxygen to form water ( oxygen is the final election receptor
33
New cards
when 2 high energy electrons transport down the electron transport chain, it causes
a charge difference across the inter-membrane space
34
New cards
the inner membrane produces _______ __which converts to__
produces ATP synthase which converts ADP to ATP
35
New cards
what is the total amount of atp in glycolysis, oxidative respiration and what do both of them add up to
glycolysis= 2 atp

oxidative respiration= 34atp

total= 36 atp

this represents 38% of glucoses energy, the rest is released as heat
36
New cards
what does fermentation do
follows glycolysis and releases energy from food molecules by producing ATP in the absence of oxygen (anaerobic)
37
New cards
cells convert NADH to NAD+ by
passing electrons back to pyruvic acid
38
New cards
what is alcoholic fermentation and what is the formula
yeast forms ethyl alcohol and carbon dioxide,

pyruvic acid + NADH → alcohol + co2 + NAD+
39
New cards
how many ATP molecules does fermentation produce
2 ATP molecules
40
New cards
what is lactic acid fermentation and whats the formula
pyruvic acid gets converted to lactic acid

pyruvic acid +NADH → lactic acid + NAD+
41
New cards
lactic acid is produced where '

and what kind of organisms make lactic acids
muscles during exercise

unicellular
