Respiration

Question 1

What is respiration

Answer 1

Transfer energy from glucose which on in every cell exothermic transfers energy to the environment

Question 2

Examples of what respiration transfers energy for

Answer 2

To build larger molecules from smaller

animals muscles to contract

In mammals and birds energy to keep body temp steady in colder environments

Question 3

What is metabolism

Answer 3

All chemical reactions in a an organisims

Question 4

Reactions where larger molecules are made into smaller ones

Answer 4

Lots of small glucose molecules are joined together in reactions to form starch . glycogen and cellulose

lipid molecules made from one molecule of glycerol 3 of fatty acids

glucose combined with nitrate ions to make amino acids then into proteins

Question 5

Reactions where smaller molecules are made into larger ones

Answer 5

Glucose broken down by respiration. Respiration transfers all of its energy to power all of reactions in body that make molecules

excess protein broken down into urea urea excreted by urine

Question 6

What is anaerobic respiration

Answer 6

incomplete breakdown of glucose when there is no oxygen

doesn’t release that much energy due to glucose not being fully oxidised

needed in emergency

glucose- lactic acid

Question 7

Anaerobic respiration in plants

Answer 7

glucose - ethanol + carbon dioxide

in plat and yeast cells

in yeast its called fermentation used to make alcohol

co2 in fermentation of bread leads to it rising
