respiration

define respiration

chemical reaction that breaks down glucose to release ATP (adenine triphosphate)

why is respiration need

muscles to contract

active transport

protein synthesis

cell division

what are the two types of respiration

aerobic respiration

anaerobic respiration

what is the word equation for aerobic respiration

glucose + oxygen —> carbon dioxide + water

what is the word equation for anaerobic respiration (in animals)

glucose —> lactic acid

what is the difference between anaerobic respiration and aerobic respiration

in anaerobic respiration

• oxygen is not required

• low ATP

• product is lactic acid

in aerobic respiration

• oxygen is required

• high ATP

• product is carbon dioxide and water.

what is the word equation for anaerobic respiration (plants)

glucose —> ethanol + carbon dioxide.

what is the chemical balanced equation for aerobic respiration

C6H12O6 + 6O2 —> 6CO2 + 6H2O

how would you investgiate to see if carbon dioxide and heat is released from respiration

get tube

fill a quarter of the tube with hydrogen carbonate indicator

get cotton and put it in the flask (dont make the hydrogen carbonate indicator touch the cotton wool)

place the germinating seeds ontop of the cotton wool and use a lid on the top of the testing tube

red —> yellow of the colour of the indicator will be the result if respiration took place.
