LEAVE ACCRUAL RECORDS. Vacation and sick leaves are accrued based on the leave accrual codes established on the Payroll Personnel System (PPS). Leave code is established by the department when an appointment is initially set up. For staff employees thereafter, the PPS will re-derive the leave code on the appointment during month-begin periodic maintenance.
For muscles to contract there needs to be an adequate supply of ATP within the cell. ATP is generated in part by a supply of glucose and oxidative phosphorylation. An inadequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction.
Adenosine Triphosphate (ATP) is the immediate source of (chemical) energy for muscle contraction. Very little ATP is stored in muscle fibres (= ' muscle cells '), only enough to power muscle contractions for a few seconds.The ATP in muscles must be constantly replenished as it is used for various processes. Glycolysis is the break-down of glucose molecules. Glucose molecules can reach muscle tissues via blood circulation. They can also be produced within muscle cells by the breakdown of glycogen molecules (glycogen being the form in which glucose is stored muscles). 3. This process. so it is described as aerobic.
