Photosynthesis, Cellular
Respiration, and a little
Fermentation
What does it take to grow
a plant???
How do we grow a plant?
But is that all????

Let’s draw the chemical formula on the
board!!
What are the reactants, What are the
products?
What type of energy transformations
are going on?
Are your cells respirating
right now???
So how do you get
glucose in your body?

And what is it exactly??
It’s a cycle in plant
cells, Jennnnay
The process of cellular
respiration is taking place in
your cells right now!!


You are currently taking in oxygen and
burning sugars within the
mitochondria to release chemical
energy.
This process is also known as Aerobic
Respiration. Why?
– Because Oxygen is present which allows
your cells to burn glucose into energy
much more efficiently.
– I am sure you have heard of Aerobics.
What would happen if your cells
were deprived of oxygen?? Would
they still be able to burn glucose to
make energy??
 YES!!
 Fermentation
– When might this occur?
– Long distance runners often create an
anaerobic environment for their cells

What does anaerobic mean??
– No Oxygen present
– Not a very energy efficient process and a
bad side effect is produced:

Lactic Acid
A different example of
fermentation

Breweries rely on this process:
– Yeast cells need energy to survive, so
they will breakdown sugars in anaerobic
conditions and a byproduct is alcohol.
– How do you know CO2 is produced?
