AQA BIOLOGY PAPER 1 UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
Question:
1. aerobic respiration
Answer:
an exothermic reaction in which glucose is broken down using oxygen to
produce carbon dioxide and water and release energy for the cells
Question:
2. anaerobic respiration
Answer:
an exothermic reaction in which glucose is broken down in the absence of
oxygen to produce lactic acid in animals and ethanol and carbon dioxide in
plants and yeast. A small amount of energy is transferred for the cells
Question:
3. exothermic reaction
Answer:
a reaction that transfers energy to the environment
Question:
4. glycogen
Answer:
carbohydrate store in animals
Question:
5. lactic acid
Answer:
the end product of anaerobic respiration in animal cells
Question:
6. oxygen debt
Answer:
the extra oxygen that must be taken into the body after exercise has stopped to
complete the aerobic respiration of lactic acid
,Question:
7. Mitochondria
Answer:
Organelle that is the site of respiration
Question:
8. Responses to exercise
Answer:
Heart rate increases, Breathing rate increases, glycogen in muscles is converted
to glucose
Question:
9. endothermic reaction
Answer:
a reaction that requires a transfer of energy from the environment
Question:
10. glucose
Answer:
a simple sugar
Question:
11. limiting factors
Answer:
limit the rate of a reaction, for example photosynthesis
Question:
12. photosynthesis
Answer:
the process by which plants make food using carbon dioxide, water, and light
Question:
13. Reactants for photosynthesis
Answer:
water and carbon dioxide
Question:
14. Products of photosynthesis
Answer:
glucose and oxygen
, Question:
15. Chloroplast
Answer:
Site of photosynthesis
Question:
16. white blood cells
Answer:
Blood cells that perform the function of destroying disease-causing
microorganisms
Question:
17. Sperm cells
Answer:
It has a long tail and a streamlined head to help it swim. There are a lot of
mitochondria in the cell to provide the energy needed. It also carries enzymes in
its head to digest through the egg cell membrane.
Question:
18. light
Answer:
energy source for photosynthesis
Question:
19. the artery that leaves the heart from the left ventricle and carries oxygenated
blood to the body
Answer:
aorta
Question:
20. arteries
Answer:
blood vessels that carry blood away from the heart. They usually carry
oxygenated blood and have a pulse
