oxygen
glucose
Photosynthesis is to chloroplasts as cellular respiration is to
chloroplasts
cytoplasm
nuclei
Which of the following is NOT a stage or cellular respiration?
fermentation
electron transport
glycolysis
Krebs cycle
The air bubbles and spongy texture of bread are due to which process?
lactic acid fermentation
alcoholic fermentation
the Krebs cycle
The Krebs cycle produces
lactic acid
carbon dioxide
the starting molecule for glycolysis is
ADP
pyruvic acid
Which of these processes takes place in the cytoplasm of a cell?
krebs cycle
photosynthesis
Glycolysis provides a cell with a net gain of
2 ATP molecules
4 ATP molecules
18 ATP molecules
36 ATP molecules
Which process does NOT release energy from glucose
cellular respiration
High-energy electrons that move down the electron transport chain ultimately provide the energy needed to
transport water molecules across the membrane
convert ADP molecules into ATP molecules
convert carbon dioxide into water molecules
break down glucose into pyretic acid molecules
How do organisms get the energy they need?
by burning food molecules and releasing their energy as heat
by breathing oxygen into the lungs and combining it with carbon dioxide
by breaking down food molecules gradually and capturing their chemical energy
by using the sun's energy to break down food molecules and form chemicals
In eukaryotes, electron transport occurs int he
inner mitochondrial membrane
nucleus
cell membrane
