- Q1
what is respiration?
it is a process which releases energy from food
it is a process which is used by plants to make food
it is a process which makes energy from food
30s - Q2
what is the word equation for respiration?
carbon dioxide + water --> glucose + oxygen
glucose + oxygen --> carbon dioxide + water
30s - Q3
what is anaerobic respiration?
respiration with oxygen
respiration without oxygen
30s - Q4
what is aerobic respiration?
respiration with oxygen
respiration without oxygen
30s - Q5
What type of reaction is respiration?
exothermic, releases energy
endothermic, takes in energy
30s - Q6
where does aerobic respiration take place?
mitochondria
cytoplasm
30s - Q7
If a cell is very active, what will it have a lot of?
mitochondria
cytoplasm
30s - Q8
what is respiration used for?
basic functions of life, building up larger molecules from smaller ones, break down larger molecules into smaller ones, muscles contract, keeping internal temperature constant and in plants to transfer mineral ions throughout the plantbasic functions of life, building up larger molecules from smaller ones, break down larger molecules into smaller ones, muscles relax, keeping internal temperature constant and in plants to transfer mineral ions throughout the plant

30s - Q9
how is excess glucose stored in our bodies?
glucagon
glycogen
30s - Q10
what happens when we exercise?
more respiration needs to occur, breathing rate increases to take more oxygen in and remove carbon dioxide, heart rate increases to provide muscles with more oxygen and glucose for the increased respiration
less respiration needs to occur, breathing rate increases to take more oxygen in and remove carbon dioxide, heart rate increases to provide muscles with more oxygen and glucose for the decreased respiration
30s - Q11
what happens when you exercise?
glucagon is broken down into glucose to supply cells with fuelglycogen is broken down into glucose to supply cells with fuel
glycogen is broken down into glucose to supply cells with fuel
30s - Q12
when does anaerobic respiration occur?
when you exercise hard
when walking
30s - Q13
which releases more energy: aerobic or anaerobic?
aerobic
anaerobic
30s - Q14
in animal cells what is produced from anaerobic respiration?
lactic acid
ethanol and carbon dioxide
30s - Q15
what is muscle fatigue?
when muscles are used slowly for a short time, lactic acid builds up because of anaerobic respiration
when muscles are used vigorously for a long time, lactic acid builds up because of anaerobic respiration
