Topic B4 - Bioenergetics

Question	Answer
What is aerobic respiration?	It is respiration that involves oxygen.
What is the equation for aerobic respiration?	Glucose + Oxygen ↓ Carbon dioxide + Water (+ Energy)
How would you test for carbon dioxide?	Breathe into lime water. If it turns from clear to milky, carbon dioxide is present.
How would you test for water?	Breathe onto a mirror. If water vapour appears, water is present.
Where does respiration occur?	Mitochondria
How does respiration occur?	Controlled by enzymes
What is anaerobic respiration?	When respiration occurs without enough oxygen.
What is the equation for anaerobic respiration in animal cells?	Glucose ↓ Lactic acid + Energy
What is the equation for anaerobic respiration in plant and yeast cells?	Glucose ↓ Ethanol + Carbon dioxide
What is oxygen debt?	The amount of extra oxygen required after exercise to react the accumulated lactic acids and remove it from the cells.
What are the side effects of oxygen debt?	Muscle fatigue and cramp.
Define metabolism	All the chemical reactions happening in a living organism.
What is the equation for photosynthesis?	Carbon dioxide + Water ↓ Glucose + Oxygen
What is chlorophyll and what does it do?	Chlorophyll is the green pigmentation found inside chloroplasts. It is absorbs sunlight for photosynthesis.
Define limiting factor	A limiting factor is a part of the photosynthesis reaction that is in short supply which presents the rate of photosynthesis increasing further.
