Oxidoreductases manage redox reactions, transferring electrons between molecules. Transferases are responsible for moving functional groups from one molecule to another. Hydrolases are able to break chemical bonds, while lyases create new bonds by removing or adding functional groups.ATP is an energy molecule, and when hydrolysis happens, it gets broken down to release the energy that was stored in its chemical bonds. Transport that directly uses ATP for energy is considered primary active transport.

Frontstage is where we perform for others, often portraying an ideal image. Backstage is our private life, where we can be ourselves. A section of the sarcomere used by the scientists. The tension in the actin between each myosin section are summed up and referred to as a single tension. The tension following myosin section 1 (M1) is referred to as TA, and the tension following myosin section 2 (M2) is TB. This section of actin is directly connected to the sarcomere’s end. Schwann cells are a type of cell that support nerve cells. They wrap around a part of the nerve cell called the axon, which helps messages move quickly and keeps the axon healthy. Some Schwann cells also provide support to smaller nerve cells without wrapping around them. They play a key role in our nervous system.
