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).
Is the production of ATP in photosynthesis similar to the production of ATP in cellular respiration? Photosynthesis is often described as the reverse of cellular respiration. Respiration breaks down complex molecules to release energy that is used to make ATP. Photosynthesis takes energy from photons and uses it to build complex molecules. However both systems use an electron transport chain and associated proton pump and ATP synthase as a key part of the process.
