Respiration N4 Flashcards
What is respiration?
The process in which cells release chemical energy trapped in food such as glucose
What can released energy be used for?
Cell activities such as cell division
What is respiration controlled by?
Enzymes
Can respiration occur without oxygen?
Yes
What is the word equation for respiration with oxygen?
Glucose + oxygen -> carbon dioxide + water + a large amount of energy
What is the word equation for respiration without oxygen in plant and yeast cells?
Glucose -> carbon dioxide + alcohol + less energy
What is the word equation for respiration without oxygen in animal cells?
Glucose -> lactic acid + less energy
What happens if oxygen is not available in respiration in animal cells?
Glucose cells get broken down into lactic acid
What happens if there is a build up of lactic acid in animal cells?
Pain and muscles not working
What is germination?
Early growth of a seed
What factors can have an effect on respiration?
pH level and temperature
If there is no sugar in yeast respiration, will it work?
No
