What is the correct sequence of events in cellular respiration?


what is released during cellular respiration?

6O2 + C6H12O6 --> 6CO2 + 6H2O + 36 ATP

what is the correct equation for cellular respiration?


which of these is a product of cellular respiration: oxygen, water, glucose, or all of the above?


what process takes place in the cytoplasm of a cell?


glycolysis provides a cell with a net gain of how many ATP molecules?


the starting molecule for glycolysis is..


which of the following is NOT a product of glycolysis: NADH, pyruvic acid, ATP, glucose


what acts as an electron carrier in cellular respiration?

muscle cells

lactic acid fermentation occurs in .....

alcoholic and lactic acid

the two main types of fermentation are called...

lactic acid fermentation

milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. What process would you expect to be key in the production of yogurt?

the Krebs cycle

in the presence of oxygen, glycolysis is followed by...

anaerobic bacterium

which organism is NOT likely to carry out cellular respiration: tree, mushroom, anaerobic bacterium, or tiger?

pyruvic acid

the starting molecule for the intermediate stage in the Krebs cycle is...


the Krebs cycle does not occur if what doesn't occur?

electron carriers

the Krebs cycle produces...

pyruvic acid and yields carbon dioxide

the Krebs cycle starts with...

cell membrane

in eukaryotes, electron transport occurs in the...


what passes high-energy electrons into the ETC?


the energy of the electrons passing along the ETC is used to make what?


which process does NOT release energy from glucose: glycolysis, photosynthesis, fermentation, or cellular respiration?

photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back

how are cellular respiration and photosynthesis almost opposite processes?


photosynthesis is to chloroplast as aerobic cellular respiration is to: chloroplast, cytoplasm, mitochondria, or nuclei

reactants of cellular respiration

the products of photosynthesis are the....


cellular respiration releases energy breaking down glucose in the presence of.....


the products of ......... are 2 ATP, 2 NADH, 2 water molecules and 2 pyruvic acid molecules

carbohydrates or glucose

either cellular respiration or fermentation can be used to release energy, depending on the presence of ........


without the Krebs cycle, the ....... would produce very few ATPs


..... and ...... carry electrons from the Krebs cycle to the ETC


during photosynthesis, energy is stored in the form of....

glycolysis, Krebs cycle, ETC

the three main stages of cellular respiration are ........, the ........, and ..........


without oxygen, a cell can extract a net gain of only .... molecules of ATP from each glucose molecule

pyruvic acid

gycolysis converts glucose into two molecules of ....


two turns of the Krebs cycle will result in .... ATP molecules


a high level of lactic acid fermentation in the blood is a sign that ........ has occurred

eukaryotic cells

cellular respiration only occurs in....

citric acid, a six carbon chain, is made during the Krebs cycle

why is the Krebs cycle also known as the citric acid cycle?

to produce 32 ATPs

what is the main function of the ETC?

it takes away four electrons and 4 hydrogens creating 2 water molecules

What role does oxygen play in the ETC?
