Cell Energy Knowledge Check

Match the process to the correct description

• fermentation

• process by which cells obtain energy from glucose by breaking down simple food molecules such as sugar and releasing the stored energy.

• cellular respiration

• releases energy without using oxygen

• photosynthesis

• using the sun's energy, plants create sugars

How is fermentation different than regular cellular respiration?

• They are the same because they go through the same process to break down glucose

• Animals can't use fermentation

• Fermentation breaks down glucose without the use of oxygen

• Fermentation doesn't produce carbon dioxide as a waste product

Imagine you've run over the Cooper River Bridge. An hour later, your leg muscles are really sore. Why? 

• When you run for a long time, your muscles may not get all the oxygen they need for cellular respiration. They still need energy, so fermentation kicks in. It produces lactic acid, which builds up in your cells. The build up of acid causes a burning sensation.

• When you run for a long time, cells get tired of going through cellular respiration. Cells have run out of glucose so they begin to die. When the cells die, it produces a burning sensation.

• When you run for a long time, your muscle cells begin to eat the fat cells as a form of energy. When the cells start eating, they swell and this is painful. This causes a burning sensation. 

• When you run for a long time, cells switch over to photosynthesis as a way to create energy for your body. This switch produces lactic acid, which builds up in your cells. The build up of acid causes a burning sensation. 

How are photosynthesis and cellular respiration similar? CHOOSE ALL THAT APPLY

• The products of cellular respiration (carbon dioxide and water) are used as the reactants (starting materials) for photosynthesis

• Photosynthesis breaks down glucose, while cellular respiration creates glucose

• The products of cellular respiration (carbon dioxide and water) are used as the reactants (starting materials) for photosynthesis

• Photosynthesis creates glucose, while cellular respiration breaks down glucose

• They don't have anything in common- they are two unrelated things

Organize these options into the right categories

Groups:

(a) Photosynthesis

,

(b) Cellular Respiration

• Produces glucose & oxygen

• Occurs in plants only

• Breaks down sugars

• Produces water & carbon dioxid

• Reactants are carbon dioxide & water

• Occurs in plants & animals

• Creates sugars

• Reactants are oxygen & glucose
