There are also organic or inorganic compounds known as co factors ...without which many enzymes won't work. In these cases the protein part of the enzyme is called the apoenzyme. There are also certain inhibitors which are required to stop the function of enzymes when not needed. When these inhibitors closely resemble the substrate. These are called competitive inhibitors. As they compete with the substrate to bind with the enzyme.

Most of the Enzymes are proteins. Their function is to catalyse a reaction. A reaction which would take a lot of time and energy to happen ...using an enzyme can take place in seconds. For eg. CO2 's reaction with water under normal conditions is very slow.. about 200 molecules of H2co3 an hour. But using Carbonic anhydrase ( an enzyme) you can form 600,000 molecules per second. Enzymes do this due to their structure. In their structure there are crevices ...known as active sites. The reactant or substrate fits in this active site perfectly. After this the bonds of the substrate are loosened so that it can form the product more easily and with less energy requirements.

This is really not the time to watch videos of everything but you should go through things like mitosis,meiosis , biomolecules ,etc. I recommend the channels bozeman science and crash course biology. Or search for animated videos ...after watching them even a breif study will be enough.

Tunicates are considered acraniate chordates because tunicates and chordates have the following features in common: a notochord; a dorsal, hollow nerve cord; and pharyngeal gill slits at some time in their lives. In vertebrates, the nerve cord becomes the spinal cord and brain. The name tunicates come from the tunic surrounding their body. The name sea squirt comes from the way water is pushed out through the exhalant siphon. ... On the inside of the epidermis are a thicker dermis (body wall) and bands of muscles which can squeeze the tunic forcing a jet of water from the exhalant siphon.

Androgens and estrogens are hormones. Estrogens are produced by the body in greater amounts in females. They are necessary for normal sexual development of the female and for the regulation of the menstrual cycle during the childbearing years. Androgens are produced by the body in greater amounts in males. Natural glucocorticoids are steroid hormones with powerful anti-inflammatory effects produced by the human body. Glucocorticoid drugs are usually synthetic compounds that have anti-inflammatory effects similar to those of natural glucocorticoids. Natural glucocorticoids are produced by the cortex of the adrenal gland. Catecholamines are hormones made by your adrenal glands, which are located on top of your kidneys. Examples include dopamine; norepinephrine; and epinephrine (this used to be called adrenalin or adrenaline).
