When you eat pasta carbohydrates will brake down into glucose. The cell will use glucose by which process?
The process of using glucose to generate energy is called
cellular
respiration.The
reactants, or what we start with, in cellular respiration are
glucose and oxygen. We get oxygen by breathing in the air. Our
bodies process cellular respiration to generate energy, which is
stored as ATP, and carbon dioxide. Carbon dioxide is a waste
product .To start the cellular respiration process, we need to
incorporate glucose into our cells. The first step is to eat
carbohydrate-rich foods, made from glucose (like Pasta). That Pasta
goes through our digestive system, where it is broken down and into
the bloodstream. Glucose travels to our cells, where it is put
inside. Once inside, cells use various enzymes, or small proteins
that speed up the chemical reaction, to convert glucose into
various molecules. The goal of this process is to extract the
energy stored in the bonds of the sugar atoms.
There are three stages of cellular respiration: glycolysis, citric
acid cycle, and oxidative phosphorylation.
