Match the process to the correct description
using the sun's energy, plants create sugars
photosynthesis
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
fermentation
Click on the location where photosynthesis occurs
Click the location where the second step of cellular respiration occurs
Because they can make their own food, plants are (a) or producers. Producers feed the (b) on Earth or those that cannot make their own food.
Through the process of photosynthesis, plants use energy from the (a) to convert (b) and (c) into (d) and (e) .
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
Reactants are carbon dioxide & water
Reactants are oxygen & glucose
Produces glucose & oxygen
Produces water & carbon dioxid
Creates sugars
Breaks down sugars
Occurs in plants only
Occurs in plants & animals
