Cells can make ATP through aerobic respiration, anaerobic respiration, or fermentation. Which of the following pathways do all three forms of cellular catabolism share? breaking down pyruvate into CO2 through a series of steps reducing pyruvate into lactic acid or acetaldehyde to regenerate NAD+ breaking down a molecule of glucose or other organic fuel into two molecules of pyruvate passing electrons through a chain of proteins to an electronegative molecule to oxidize NADH

Which of the following statements about the aerobic respiration of a molecule of glucose is FALSE? O It requires pathways and membrane complexes in both the cytosol and mitochondria in eukaryotes. O 34 molecules of ATP are generated by oxidative phosphorylation. O It requires pathways and membrane complexes in the cytosol and plasma membrane in prokaryotes. O It can generate 38 molecules of ATP in prokaryotes. O 12 molecules of ATP are generated by substrate-level phosphorylation.

An anaerobic prokaryotic cell is able to generate a maximum of how many molecules of ATP from the catabolism of one glucose molecule into two molecules of ethanol? 2 molecules of ATP 4 molecules of ATP 6 molecules of ATP 30 molecules of ATP 32 molecules of ATP

The complete catabolism of glucose into CO2 and H2O generally yields a smaller amount of ATP in aerobic eukaryotes than in aerobic prokaryotes because the aerobic eukaryotes: generate more molecules of FADH2 during aerobic respiration have transport costs to get NADH into the mitochondrion generate more molecules of NADH during aerobic respiration are able to use pyruvate as a substrate for fermentation always produce ethanol rather than lactic acid as a byproduct

Which of the following best describes the net transfer of energy that occurs during the process of cellular respiration? solar energy from the sun is converted into chemical energy that is stored in the bonds of glucose molecules chemical energy that is stored in the bonds of glucose molecules is converted to energy stored in ATP molecules energy stored in the bonds of ATP molecules is released by breaking off the bond with the last phosphate group during cellular respiration Thermal energy from making smores is converted into chemical energy in the bonds of glucose molecules

Inhibition of cytosolic functions forming lactate will cut off supplies for mitochondrial processes. B. Disruption of glucose transport across the cell membrane will decrease ATP production by mitochondria. C. Inhibition of mitochondrial function will cut off all ATP supplies for cytosolic processes. D. An increase in glucose transport across the cell membrane will decrease CO₂ production by mitochondria. SUBMIT
