Source(s): Riding for 31yrs Training for 20yrs. A horse can carry an absolute MAXIMUM of 20% of it's weight. For example, if a mini weighed 300 lbs, he could carry a maximum of 60 lbs, including the saddle, meaning that the rider would have to weigh 40 lbs for english or 30 for western.
This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
Cellular respiration occurs in three distinct, yet interconnected,  series of reactions: glycolysis, the citric acid cycle, and the  electron transport chain.   Gluc â¦ ose and oxygen are required for cellular  respiration; the products of these reactions include CO2, water,  and energy.ellular respiration occurs mainly in the mitochondria. The mitochondria is the powerhouse of the cell, which creates all of the energy (which makes sense why cellular respira â¦ tion mainly occurs there).
