Topic 4. Biology Test (Aerobic andAnaerobic Respiration)
cellular respiration - answer Process that releases energy by breaking down glucose
and other food molecules in the presence of oxygen
Inputs and outputs of cellular respiration - answer inputs: glucose, oxygen
outputs: co2, ATP, water
what is the difference between respiration and cellular respiration? - answer- Cellular
respiration takes place at the level of a cell, more specifically inside the mitochondria.
- So, oxygen is needed for this
- its basically taking our food and then breaking it down in the presence of oxygen to
make ATP out of it
aerobic respiration - answer- Process that REQUIRES the addition of oxygen to make
energy (we respire aerobically)
- the process by which organisms use oxygen to turn fuel, such as fats and sugars, into
chemical energy.
anaerobic respiration - answerProcess that does NOT require the addition of oxygen to
make energy (some bacteria and fungi respire anaerobically)
What is respiration used by? - answer- all cells to turn fuel into energy that can be used
to power cellular processes.
- the product of respiration (ATP) uses the energy stored in its phosphate bonds to
power chemical reactions. It is often referred to as the "currency" of the cell.
Why is aerobic respiration more efficient than anaerobic? - answer- produces ATP
much more quickly than anaerobic respiration.
- This is because oxygen is an excellent electron acceptor for the chemical reactions
involved in generating ATP.
what uses aerobic respiration? - answerAnimals, plants and aerobic bacteria produce
ENERGY & carbon dioxide gas
what uses anaerobic respiration? - answer- Fermentation in fungi (alcohol & CO2)
- Lactic Acid in animals and bacteria (lactic acid)
where does aerobic cellular respiration take place? - answerIt actually takes place in
two parts of the cell:
- Glycolysis occurs in the Cytoplasm of the cell
