Cellular Respiration is a process that consists of three distinct steps. 28 is the first step, in which
glucose is broken up into two 29 molecules. This step also produces the electron carrying compound,
30 and the energy storing compound, 31 . The three-carbon molecules enter the 32 , the organelle
which is considered to be the location of cellular respiration. Prior to entering the
33 which is
located in the 34 of the mitochondrion, the molecule must be converted to 35 . This conversion
loses a carbon in the form of 36 .
The Krebs Cycle produces a total of eight 37 molecules, two 38 electron-carrying molecules,
and two 39 energy storage molecules. The electron-carrying molecules will be important in the 40 ,
which consists of a series of proteins in the folds of the inner membrane, known as the 41 .
Each 42 compound can generate 3 ATP, due to the fact that the electrons from this compound
travel through three membrane proteins. The passage of an electron through each of these proteins
allows for a 43 to pass through the membrane and into the 44 , developing an uneven distribution of
ions on each side of the membrane or a (an) 45 gradient.
