CELLULAR RESPIRATION
|
: the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen cellular respiration requires the same exchange of gases, only within the living cell.
|
|
|
AEROBIC
|
a process that requires oxygen. The Krebs cycle and electron transport chain are both aerobic. Even though the Krebs cycle does not directly need oxygen, it cannot run without the electron transport chain, which does need oxygen.
|
|
|
ANAEROBIC
|
a process that does not require oxygen. Also means “without air” Glycolysis, does not need oxygen.
|
|
|
Where do organisms get energy
|
: Organisms get the energy they need from food.
|
|
|
what is cellular respiration?
|
Cellular respiration is the process that releases energy from food when oxygen is present.
|
|
|
What is the relationship between photosynthesis and cellular respiration?
|
Photosynthesis produces food molecules and removes carbon dioxide from the air, and cellular respiration puts it back. Photosynthesis gives off oxygen, and cellular respiration uses that oxygen to release energy from food.
|
|
|
cellular respiration
|
A process that needs oxygen to take place is called
|
|
|
anaerobic
|
Glycolysis is anaerobic because it can happen when there is no oxygen.
|
|
|
Do plant cells carry out cellular respiration?
|
yes, cellular respiration takes place in the mitochondria (which plant cells have) and is the process of changing nutrients, such as sugar, to usable energy (ATP)
|
|
|
How are the equations for cellular respiration and phososynthesis similar?
|
They both involve the exchange of the gases; oxygen and carbon dioxide
Photosynthesis: 6CO2 + 6H2O + Energy → C6H12O6 + 6O2 Cellular respiration: C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy |
|
|
How are they different?
|
Cellular respiration is balanced by photosynthesis. The energy from each process flows in opposite directions. The equations for photosynthesis ad cellular respiration are the reverse of each other. Photosynthesis removes carbon dioxide from the air. Cellular respiration puts it back. Photosynthesis gives off oxygen and makes sugars. Cellular respiration uses that oxygen to get energy from sugars.

|
|
Aerobics is a kind of exercise that involves rhythmic movement and stretching, usually to music. What does the name aerobics tell you about this kind of exercise?
|
This type of exercise requires oxygen. The aerobic process depends on the Krebs cycle and electron transport chain.
|
|
|
If whales stay underwater for 45 minutes or more, do you think they mostly use aerobic or anaerobic processes?
|
They mostly use the glycolysis stage of cellular respiration which is anaerobic, or ‘without air”.
