The process by which food molecules (glucose) are broken down in the muscle cells to release energy for work is called cellular respiration. There are two types of cellular respiration: aerobic (requires oxygen) and anaerobic (does not require oxygen).When the muscles are working , the body turns adenosine diphosphate (ADP) into adenosine triphosphate (ATP). ATP is then used as a source of energy, a requirement of muscle contraction. (ATP production is measured in moles, a specific unit of measurement.) Figure 1 shows the activity of the two biochemical processes that provide ATP as a function of the intensity of a workout.Aerobic respiration produces 18 times more ATP per glucose molecule than does anaerobic respiration. However, the process requires plenty of oxygen and is much more time consuming. Although anaerobic respiration is far less efficient, it is the fastest way to generate ATP. Table 1 shows the sources of glucose that are used during both types of respiration. An individual's fitness level can be determined by measuring the maximum amount of oxygen that can be used in 1 minute of activity per kilogram of body weight, also known as VO2 max. Figure 2 shows the milliliters of oxygen that can be consumed in 1 minute per kilogram of body weight for both females and males at "Poor" and "Excellent" fitness levels.
Scenаriо 4 A prоvider electrоnicаlly orders Celexа for a patient with depression. During medication verification, a pharmacy technician notices that another employee selected Celebrex from the medication database. The error is caught before dispensing. The pharmacy manager uses the event as a teaching example regarding medication safety strategies. If a provider prescribes an antidepressant for neuropathic pain, this is best described as:
