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.
Most of the ATP produced in cellular respiration come from oxidative phosphorylation, in which the energy released from redox reactions in an electron transport chain is used to produce ATP. In substrate level phosphorylation, an enzyme directly transfers a phosphate group to ADP from an intermediate substrate. All ATP production in glycolysis occurs by substrate-level phosphorylation, this form of ATP production also occurs at one step in the citric acid cycle.
