Question 3

in what form is energy transferred during respiration?

Answer 3

ATP

Question 4

What is ATP and where is it stored

Answer 4

is a molecule that is produced during respiration and provides energy in living organisms found in the mitochondria

Question 5

word equation for anaerobic respiration

Answer 5

glucose –> lactic acid

Question 6

practical (investigating the evolution of carbon dioxide and heat from respiring seeds or other suitable living organisms

Answer 6

-take two vacumn flasks making sure theres no air left in the flash sealing the top with cotton wool

-place germinating seeds in one jar and boiled seeds in the other

-record the temperature of each flask daily for a weak

-repeats should be carried out using the same mass of beans each time

-when the germinating beans respire the test flasks temperature will increase compared to the control flask
