Respiration

Question 1

the energy transferred by ATP can be used for

Answer 1

Muscular contraction
Active transport of molecules
Transmission of nerve impulses
Synthesis of proteins

Question 2

aerobic respiration equation

Answer 2

glucose + oxygen —> carbon dioxide + water + energy

Question 3

stage one of aerobic respiration

Answer 3

glucose 
     |
     |
     |
pyruvate 

stage 1 takes place in the cytoplasm
2 ATP are made
Does not require oxygen

Question 4

stage 2 of aerobic respiration

Answer 4

pyruvate 
                  |
                  |
                  |
carbon dioxide and water 

stage 2 takes place in the mitochondria
many ATP are made

Question 5

stage one of fermentation in animal cells

Answer 5

glucose 
      |
      |
      |
pyruvate 

stage 1 takes place in the cytoplasm
2 ATP are made

Question 6

stage 1 of fermentation in animal cells

Answer 6

glucose 
      |
      |
      |
pyruvate 

stage 1 takes place in the cytoplasm
2 ATP are made

Question 7

stage 2 of fermentation in animal cells

Answer 7

pyruvate
  |       ^
  |       |
  |       |
lactate

no ATP is made
stage 2 takes place in the cytoplasm

Question 8

stage 1 of fermentation in plant and yeast cells

Answer 8

glucose 
      |
      |
      |
pyruvate 

stage 1 takes place in the cytoplasm
2 ATP are made

Question 9

stage 2 in plant and yeast cells

Answer 9

pyruvate 
      |
      |
      |
carbon dioxide + ethanol 

no ATP is made during this stage
stage 2 takes place in the cytoplasm
