Respiration

Question 1

What is respiration?

Answer 1

Chemical reaction that occurs in mitochondria off all living cells to release energy for living functions and processes

Question 2

What type of reaction is it? (Exothermic or endothermic)

Answer 2

Exothermic which means energy is released to the surrounding

Question 3

What are the types of respiration and how are they different?

Answer 3

Aerobic (uses oxygen) and anaerobic (doesn’t use oxygen).

Question 4

What’s the aerobic word and symbol equations? (Balanced)

Answer 4

Glucose + oxygen —> carbon dioxide + water + energy

C6H12O6 + 6O2 —> 6CO2 + 6H2O + ATP

Question 5

What’s the anaerobic word and symbol equation? (Balanced)

Answer 5

Glucose —> lactic acid + energy

C6H12O6 —> 2C3H6O3 + ATP

Question 6

Why does anaerobic respiration release less energy than aerobic respiration?

Answer 6

In anaerobic respiration there isn’t any oxygen so the glucose can’t be fully oxidised.

Question 7

In plants and yeast how does fermentation happen and what is it used for?

Answer 7

When they anaerobically respirate is produces ethanol and carbon dioxide which are used in bread making (to make it rise) and beer brewing (create alcohol).

Question 8

What is the word and symbol equation for anaerobic respiration in yeast and plants? (Balanced)

Answer 8

Glucose —> ethanol + carbon dioxide + energy

C6H12O6 —> C2H5OH + CO2 + ATP

Question 9

What’s ATP?

Answer 9

The principal molecule for storing and transferring energy in cells.
