respiration

Question 1

aerobic respiration

Answer 1

takes place all the time in animal and plant cells
exothermic reaction

Question 2

equation for aerobic respiration

Answer 2

glucose+ oxygen = carbon dioxide + water
C6H12O6 + 6O2 =6CO2+ 6H2O

Question 3

What is the transferred energy used to do

Answer 3

build larger molecules from smaller molecules
enable muscle contraction in animals
maintain a constant body temp
move materials such as mineral ioms
build sugars, nitrates into amino acids then proteins

Question 4

how do muscles store glucose

Answer 4

as glycogen

Question 5

why do your muscles need more energy when you exercise

Answer 5

so they can contract

Question 6

anaerobic respiration

Answer 6

glucose is not completely broken down
glucose= lactic acids

Question 7

what happens if you get a build up of lactic acid

Answer 7

oxygen debt

Question 8

metabolic reactions for the conversion of small molecules into larger molecules

Answer 8

glucose to starch, glycogen or cellulose
fatty acids and glycerol to lipids
glucose and nitrate ions to amino acids
amino acids to protein

Question 9

how is urea produced

Answer 9

excess amino acids are carried to the liver. the amino group is removed in the process of deamination producing ammonia, which is toxic and is converted to the urea
