Muscle Contraction Tutorial/Review
Muscle Contraction Tutorial/Review
1. Hydrolysis is the decomposition of a substance by the insertion of water molecules between certain of its bonds. The third phosphate is removed by hydrolysis and free energy is released. ADPneedds to have another phosphate molecule in order to become ATP and this happens through hydrolysis. This ATP can be used in the muscle contraction and relaxation.
2. When one flexes his/her arm, the muscle on top is the bicep. The origin of the bicep is at the tubercule of the scapula and the insertion is at the bursa. The tricep is the muscle that is at the bottom of your arm. The origin is at the humerus and the insertion is into a white tendon that is attached to the ulna.
3. Antagonistically, referring to the bicep and tricep, means that they do opposite jobs, yet work for the same goal, which is the movement of the arm. They don’t necessarily work against each other, but with each other in opposite motions.
4. This muscle is in a relaxation state because the striations are long and uninterrupted. They are at their normal long length. This means that the myosin has not binded to the actin.
5. Nerves are the autonomic branch of the nervous system. They lead to both smooth and cardiac muscle. They regulate the strength and rate of muscle contraction.Muscle Contraction Tutorial/Review

    The four muscles of the rotator cuff are the Supraspinatus, which originates above the spine of the scapula and inserts on the greater tuberosity of the humerus. This muscle abducts the shoulder joint and also helps stabilize the head of the humerus in the glenohumeral joint. The second muscle is the Infraspinatus, which originates below…

    This principle is called the length–tension relationship. The reasons for it can be seen in figure 1.2. If a fiber is overly contracted at rest, its thick filaments are rather close to the Z discs. The stimulated muscle may contract a little, but then the thick filaments butt against the Z discs and can go no farther. The contraction is therefore a weak one. On the other hand, if a muscle fiber is too stretched before it is stimulated, there is relatively little overlap between its thick and thin filaments. When the muscle is stimulated, the myosin heads cannot “get a good grip” on the thin filaments, and again the contraction is…

    Muscle contractions happen when muscle fibers are stimulated, which can cause one of many types of contractions. Isometric contractions, which means that tension happens in the muscle but there is no change in muscle length, therefore there is no movement of the muscle itself. An example of Isometric contractions would be strength training, such as holding a weight still, which happens in the biceps brachii. The biceps brachii the gets more tension, but the muscle length stays the same. As for isotonic contractions, which means that tension is in the muscle while there is a change of length, can be split into two types: Concentric contraction, in which the tension causes the muscle to shorten, and eccentric, in which the tension causes the muscle to elongate.…

    The energy in ATP can be released as heat or can be used in the cell as a power source to drive various types of chemical and mechanical activities. For example, when the terminal phosphate group of the ATP molecule is removed by hydrolysis (a decomposition process that occurs when a substance reacts with water), energy in the form of heat is released and adenosine diphosphate (ADP) and inorganic phosphate (Pi) are formed.…

    Living organisms including all plants and animals require energy for their cellular processes. In biological processes, the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of a catabolic reaction is respiration where large molecules are broken down into smaller ones with energy released. An example of an anabolic reaction is photosynthesis where small molecules are built up into larger ones using energy. ATP is built up from ADP and inorganic phosphate ions (3-4 PO, abbreviated to Pi) by condensation and is then hydrolysed by the enzyme ATPase to ADP and Pi to release energy that can be used for energy requiring reactions such as photosynthesis in plants.…
