Chapter 4: Energy from respiration Flashcards
Which is used most of the time? Areobic Respiration or Anareobic Respiration?
Areobic Respiration
What are the waste products of Areobic Respiration?
Water and Carbon Dioxide
What does Areobic Respiration require?
Glucose and Oxygen
Where does Areobic Respiration take place inside the cell?
The mitochondria
How are mitochondria adapted to increase the rate of the Areobic Respiration reaction?
They have a folded inner membrane to increase surface area.
What is Areobic Respiration carried out by?
Enzymes.
What do we need from Areobic Respiration?
Energy.
3 examples of energy use inside an organism?
- Synthesis reactions (Building of proteins), 2. Making muscles contract. 3. Homeostasis; regulating temperature
How is glucose stored in the muscles?
It is stored as the carbohydrate “glycogen”
What changes occur inside the body during exercise? Why?
Heart rate increases, muscle arteries dilate to supply more glucose to your muscles and remove carbon dioxide, and your breathing rate increases for the same reasons.
What happens to the heart and lungs when regularly exercised?
They become larger and more powerful. They do not have to work as fast.
When does Anaerobic respiration take place?
When there is not enough oxygen
What happens in Anaerobic respiration?
Glucose is broken down into lactic acid and energy, rather than energy and carbon dioxide
What is the waste product of Anaerobic respiration
Lactic acid
How is lactic acid removed from muscles?
Oxygen is used to break it into water and carbon dioxide
