The Calvin Cycle Plants use energy from the sun in tiny energy factories called chloroplasts. Using chlorophyll in the process of photosynthesis‚ they convert the sun’s energy into storable form in ordered sugar molecules such as glucose. In this way‚ carbon dioxide from the air and water from the soil in a more disordered state are combined to form the more ordered sugar molecules. Carbon dioxide is captured in a cycle of reactions known as the Calvin cycle or the Calvin-Benson cycle after its

Cardiac Cycle The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles
