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.
Your body needs enzymes to function. The CPK isoenzymes test is a way to measure the levels of an enzyme called creatine phosphokinase (CPK) in your blood. CPK can be broken down into three distinct parts: 1  CPK-1 comes mainly from the brain and lungs. 2  CPK-2 is mainly from the heart. 3  CPK-3 is from skeletal muscle.
