(Select all that apply)
animals
yeasts
plants
all of the above
|
Which of the following is a consequence of lactic acid accumulation in muscle tissue?
increased pH affecting enzymes
increased ATP production
improved muscle function
cramp and muscle fatigue
|
What happens to lactate produced during lactate fermentation in mammals?
(Select all that apply)
it is removed as a waste product
it is stored as glycogen
it is reduced
it is oxidised back to pyruvate to generate more ATP
|
What is the approximate yield of ATP per glucose molecule in anaerobic respiration?
2 ATP
16 ATP
4 ATP
32 ATP
|
Why can't oxidative phosphorylation and the Krebs cycle continue in anaerobic conditions?
the enzymes required for these processes are not present
the mitochondria are not functioning properly
all the FAD and NAD will be reduced and cannot accept protons and electrons
there is not enough glucose available
|
In which organisms can alcohol fermentation occur?
(Select all that apply)
animals
yeasts
plants
all of the above
|
Which of the following are difference(s) between aerobic and anaerobic respiration?
(Select all that apply)
aerobic respiration yields less ATP per glucose molecule
aerobic respiration includes the link reaction, Krebs cycle, and oxidative phosphorylation
anaerobic respiration requires oxygen
anaerobic respiration occurs only in the cytoplasm
|
Which of the following is true about anaerobic respiration?
it acts as an emergency measure for ATP production when oxygen levels are low
it yields more ATP than aerobic respiration
it requires oxygen
it occurs only in the mitochondria
