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.
Test: CPK, Creatine Phosphokinase (CK) Creatine Kinase. This is a blood chemistry test to measure the amount of enzyme in the blood. The CPK enzyme is found in high concentration in heart and skeletal muscle; low concentration is brain tissue. CPK is an enzyme that catalyzes the creatine-creatinine metabolic pathway in muscle cells and brain tissue.
