cellular respiration checkup

QuestionAnswer
chem. equation for cellular respiration ? C6H12O6 + 6O2 -----> 6CO2 + 6H2O
principal energy source for cells ? glucose
glucose cant be used to directly power cells: true or false ? true
cells break down glucose to produce what ? ATP
what does ATP stand for ? adenosine triphosphate
cellular respiration is... a complicated series of the aerobic, or oxygen using, breakdown of glucose
where does cellular respiration occur ? the first stage is in the cytoplasm of the cell but the other stages are in the mitochondria
sometimes glycolysis isn't followed by the Krebs Cycle but... an anaerobic process known as fermentation
fermentation requires ATP: true or false ? false
why does ATP regenerate the molecules necessary to keep glycolysis going ? bc it allows cells to obtain ATP through glycosis
the ATP molecule consists of... an adenine unit, a ribose unit, and a 3-phosphate chain
first step of process ? anaerobic where glycolysis in cytoplasm (glucose transforms into pyruvate)
second step of process ? aerobic process where pyruvate oxidizing into ATP and other molecules in mitochondria
third step of process ? aerobic process where electrons transferred create a proton gradient to power ATP synthase in mitochondria
aerobic cellular respiration happen in both plants and animal cells: true or false ? true
where do plants get inputs for aerobic cellular respiration ? energy from sunlight powers photosynthesis which provides glucose
where do animals get inputs for aerobic cellular respiration ? breaking down food they eat (specifically glucose)
