Respiration

Question 1

What is respiration?

Answer 1

Inside cell 🧫🧬energy is released by the breakdown of glucose🍞

Question 2

What takes place if oxygen is not present?

Answer 2

Fermentation

Question 3

What takes place if oxygen is present?

Answer 3

Aerobic Respiration

Question 4

Describe the 1 stage of aerobic respiration

Answer 4

Stage 1 : Glycolysis (in the cytoplasm) where 2 ATP is produced & glucose is broken into 2 pyruvate

Question 5

Describe the 2nd stage of Aerobic Respiration

Answer 5

Stage 2 : Breakdown of pyruvate (in the mitochondria) 2 pyrvates broken in Water & Carbon Dioxide & Large ATP is produced
‼️ oxygen needed‼️

Question 6

Describe the 1 stage of fermentation

Answer 6

Stage 1 : Glycolysis (in the cytoplasm) where 2 ATP is produced & glucose is broken into 2 pyruvates

Question 7

Describe the 2nd stage in fermentation

Answer 7

Stage 2 : Breakdown of pyruvate (in the cytoplasm ) 2 pyrvates broken into Lactate & Ethanol + CO2 & No ATP produced
‼️ oxygen not needed‼️

Question 8

What does the animal cell produce in fermentation?

Answer 8

Lactate Acid

Question 9
