Â· just now. Report Abuse. 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. Minis are not meant for riding (unless it's a baby or or small child).
Learning Objectives. We have just discussed two pathways in glucose catabolismâglycolysis and the Krebs cycleâthat generate ATP by substrate-level phosphorylation. Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration.
production of ATP. In your response, consider which process produces ATP and which process contributes to its production. The three sources are ATP already in muscles, ATP made by lactic acid fermentation, and ATP produced by cellular respiration. After the ATP in muscles is used, the muscles produce ATP by lactic acid fermentation. Lactic acid fermentation produces lactic acid as a byproduct. of the lactic acid is in a chemical pathway that requires extra oxygen. Cellular respiration is the only way to continue generating a supply of ATP.
