Answer 0

C6⃣H1⃣2⃣ + 6O2⃣ ➡️ 6CO2⃣ + 6H2⃣O + energy
1 sugar / 6 Oxygen / 6 Carbon / Water
/ / Dioxide /

Question 1

What happens during respiration?

Answer 1

During respiration, cells break down simple food molecules such as sugar and release the energy they contain.

Question 2

Explain why cellular respiration adds carbon dioxide while photosynthesis doesn’t?

Answer 2

Cellular respiration uses the oxygen it consumes, so it can’t release it.

Question 3

What is the process in which cells obtain energy without using oxygen?

Answer 3

Fermentation is the process in which cells obtain energy without using oxygen.

Question 4

How would athletes be affected if fermentation couldn’t take place?

Answer 4

The cells would shut down from lack of oxygen.

Question 5

Is this process more likely to occur during a long walk, or a short run?

Answer 5

During a short run because your muscles are working harder and your cells are using up oxygen faster than it is produced.

Question 6

What is respiration?

Answer 6

The process by which cells obtain energy from glucose.

Question 7

What is fermentation?

Answer 7

An energy releasing process that doesn’t require oxygen.
