Karten in diesem Stapel (15)
- 1What is Aerobic Respiration?Respiration with Oxygen
- 2What is Anaerobic Respiration?Respiration without Oxygen
- 3What is Respiration?The process of transferring energy from food molecules in every living cell
- 4What is the word equation for Aerobic Respiration?Glucose + Oxygen = Carbon Dioxide + Water + (energy)
- 5What is the word equation for Anaerobic Respiration?Glucose = Lactic Acid + (little energy)
- 6What does Respiration do?A series of reactions that release energy for cells from Glucose
- 7What happens during exercise?The breathing rate, heart rate and depth of breathing all increase.
The increased heart rate increases the rate of blood flow around the body. The increased rate and depth of breathing increases the rate of gaseous exchange in the lungs. - 8When does Aerobic Respiration happen?It happens all the time in the cells of animals and plants
- 9What happens during Aerobic Respiration?Glucose and Oxygen are used up
Carbon Dioxide and water are produced as waste products - 10Where does Aerobic Respiration take place?It takes place inside Mitochondria which is inside the cytoplasm of the cells
Controlled by enzymes - 11What happens to the energy released during Respiration? (Plant specific)It may bee used to build up large molecules from smaller ones
eg…
Plants make amino acids from sugars, nitrates and other nutrients - which build up larger molecules (proteins) - 12What happens to the energy released during Respiration? (Animal specific)Enables muscles to contract so animals can move
Keeps body temperature steady (when surroundings are colder than them) - 13What happens during exercise? (muscle cells respire more than at rest)Oxygen and Glucose must be delivered more quickly to the muscle cells
Waste Carbon Dioxide must be removed more quickly - 14How is Glucose stored?In animals: muscles store glucose as glycogen (converted back during exercise)
In plants: glucose stored as starch - 15What is the difference between Respiration and Breathing?Respiration releases energy
Breathing lets air into and out of our lungs
