a series of reactions in which part of it is broken down into carbon dioxide is what cycle?
Krebs cycle
what high-energy electron carrier is regenerated during fermentation that allows cells to continue to make ATP using glycolysis?
NAD+
two molecules of ATP and two molecules of ______ are formed from every glucose molecule that is broken down.
NADH
the mitochondria is sometimes referred to as the what
Powerhouse
a process that requires oxygen is
aerobic
because cellular respiration requires oxygen it is said to be
aerobic
what types of organisms utilize cellular respiration?
all types of organisms
is glycolysis aerobic or anaerobic?
anaerobic
since fermentation does not require oxygen it is
anaerobic
what gas is produced in the transition reaction?
carbon dioxide
organisms obtain energy in a process called
cellular respiration
where does glycolysis occur?
cytoplasm
where does glycolysis take place?
cytoplasm
where in the cell do the reactions of cellular respiration occur?
cytoplasm and the mitochondria
what stage of cellular respiration produces the most ATP?
electron transport and chemiosmosis
ATP is used to provide ______ for cells to do work.
energy
true or false the hydrogen necessary in the electron transport chain comes from the splitting of carbon dioxide molecules.
false NADH and FADH2 come from the splitting of molecules
true or false electron transportation is the first step in the breakdown of glucose
false, It's the final step
true or false alcohol fermentation is found in some bacteria and in humans.
false, bacteria and in yeast
true or false fermentation occurs in the mitochondria.
false, it occurs in the cytoplasm
if oxygen is not present, glycolysis is followed by
fermentation
what is split in glycolysis?
g3p
in glycolysis what is broken down into pyruvate?
glucose
cellular respiration harvests electrons from carbon compounds, such as ______ and uses the energy to make_______.
glucose, ATP
what is the first step in cellular respiration that begins releasing energy stored in glucose?
glycolysis
where does the electron transport chain occur?
inner membrane
what is FAD
it's another electron carrier similar to NAD and nadp

lactic acid fermentation
aerobic respiration takes place in the_________.
mitochondria
where does the transition reaction occur?
mitochondria
where does the Krebs cycle occur?
mitochondrial matrix
an anaerobic process does not require_______.
oxygen
what gas is used in the electron transport chain?
oxygen
during glycolysis, glucose is what?
partially broken down and some of its stored energy is released
what is cellular respiration?
process in which organic compounds are broken down by cells to release energy to make ATP.
name the 3 carbon molecule produced when glucose is broken down in half during glycolysis
pyruvate
what is lactic acid fermentation?
pyruvate is converted into lactic acid
what is alcohol fermentation?
pyruvate is converted to ethyl alcohol and carbon dioxide.
what are the end products of glycolysis?
pyruvate, ATP, and nadh
lactic acid fermentation occurs in ______ ______ cells.
skeletal muscles
what chain pumps protons into the space between the inner and outer mitochondrial membranes?
the electron transport chain
why does fermentation occur?
there's no Oxygen
what is the main purpose of fermentation?
to regenerate NAD+ to be used in Glycolysis
true or false skeletal muscle produces lactic acid when the body cannot supply enough oxygen.
true
true or false the Krebs cycle is sometimes called the TCA cycle or the citric acid cycle.
true
true or false the anaerobic pathway that follows glycolysis in the absence of oxygen is fermentation.
true

two are needed to repay to start
what substance is made during the electron transport chain?
water
alcohol fermentation occurs in
yeast and bacteria
