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.
Both reactions are accomplished in organelles; chloroplasts are the sites of photosynthesis, and cellular respiration happens mainly in the mitochondria. Only photosynthetic organisms can make glucose, but all organisms must be able to use that energy. This energy usually comes in the form of ATP, or adenosine triphosphate. Cellular respiration produces ATP. The glucose is burned to produce the ATP. Cellular respiration consists of four steps.
