Making energy from the ultimate energy source. Photosynthesis is the process by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel. Here is how it works. The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun.
The creatine phosphokinase test measures the amount of creatine phosphokinase (CPK) present in the blood. The test is also known as creatine kinase, CPK test, and CK test.
The CPK isoenzymes test measures the different forms of creatine phosphokinase (CPK) in the blood. CPK is an enzyme found mainly in the heart, brain, and skeletal muscle. A blood sample is needed. This may be taken from a vein. The test is called a venipuncture. If you are in the hospital, this test may be repeated over 2 or 3 days. A significant rise or fall in the total CPK or CPK isoenzymes can help your health care provider diagnosis certain conditions.
