So now that you have a good understanding of the general
pathway for cellular respiration,
lets talk a little bit about some of the other fuels
that we might need to catabolize or breakdown in order to
obtain energy, make ATP. By the end of this lecture, you
should be able to identify the various entry points
for proteins as well as fats in cellular respiration and
describe some key intermediates in the cellular
respiration pathway where these molecules enter. Finally,
you should be able to recognize how cellular respiration
can be modulated by negative feedback mechanisms
We're very familiar already with the general central view
of the metabolism of carbohydrates.
We'll revisit those a little bit in this lecture. However,
the main emphasis is going to be where fats and protein
fit into the scheme of things. Because we all know in our
dietary intake, we will generally have
a proportion of carbohydrates, and we'll also consume
some fats as well as proteins.
So it's important to understand how they are broken
down and how they fit into the scheme of things.
