Cellular respiration:

Glycosis:

First stage of the metabolic pathway of cellular respiration= ATP production

• begins breaking down sugar

• Uses two ATP to create 4 ATP

• occurs in the cytoplasm

krebs cycle:

second stage of metabolic pathway

continues breaking down sugars

two ATP- transport to mitochondria

Electron transport chain:

Electrons are sent through mitochondrial membrane. Flow of hydrogen ions into the inner membrane spaces

electrons-protein assembly-cristate: inner membrane of mitochondria

electrons go from high to low energy

eventually picked up by oxygen

hydrogen ions flow out of the membrane through an enzyme

During electron transport chain:

pumping hydrogen: hydrogen ions rush back into the mitochondrial matrix through ATP synthase, oxygen then bonds with leftover hydrogen to form water.

Cellular respiration

Cellular respiration is the metabolic process that cells use to break down glucose and other food molecules with oxygen to release chemical energy in the form of ATP (adenosine triphosphate

• All living organisms perform cellular respiration, including plants, animals, fungi, protists, and bacteria.

• Even though plants make their own food through photosynthesis, they also perform cellular respiration to turn that food into usable energy
