1.1 Glutamine: muscle metabolism Skeletal muscle is the major tissue responsible for glutamine synthesis in the body [9‚10]. In this context‚ glutamine anabolic effects in the skeletal muscle not only preserve lean mass‚ but also maintain plasma glutamine concentration in the body. Glutamine provides energy substrate to cells with a high turnover‚ nucleic acid precursors to cells of the immune system and is involved in the maintenance of acid-base balance [9‚ 11‚ 12]. The key enzymes in the metabolism

Investigating a factor that affects the rate of enzyme activity Enzymes speed up reactions. They have an area with a very particular shape called the ‘active site’. When the right molecule comes along (substrate molecule) it will fit perfectly into the active site and there will be a reaction. After the reaction the products then leave the active site. This process is often referred to as the lock and key theory as only one enzyme can carry out one type of reaction. The catalase enzyme speeds

Human activities that may affect water ecosystems such as oceans FISHING Reducing the fish communities in rivers and oceans‚ destructive fishing techniques can also cause water pollution and damage to coral and other aquatic life. Destructive fishing techniques involve the use of dynamite or cyanide; trawling in coral-rich ecosystems; bottom trawls that are dragged along the ocean floor‚ also disrupt and damage critical habitats.

Have you like me tried to build and gain muscle ‚ or maybe you just looking for a bit more info on the subject.

When it comes to muscle contraction‚ contraction takes place in the muscle fibers. Muscle fibers are the basic building blocks of the muscle and what allow muscles to contract. They appear as long cylinder cells that contain several nuclei. Contraction happens when the muscle receive signals from the nervous system and the Neuromuscular Junction obtains the muscular exchange where the synaptic bulb and the muscle fibers connect. muscle fibers are composed of myofibrils‚ which contain contractile

were more or less resistant for the muscle group being used. Valley Center High School physiology students conducted experiments on muscle size and strength and muscle fatigue. With this in mind‚ the data the students collected from these labs and other sources shows how muscle size and sex have an impact on an individual’s muscle fatigue resistance. First‚ the muscle size of an individual determines how long they can withstand certain types of physical activity. For example‚ an article from the source

When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. the brain as a central computer that controls all bodily functions‚ then the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this through the spinal cord‚ which

Bones in our body are living tissue. They have their own blood vessels and are made of living cells‚ which help them to grow and to repair themselves. Every single person has a skeleton made up of many bones. These bones give your body structure‚ let you move in many ways‚ protect your internal organs‚ and more. As well‚ proteins‚ minerals and vitamins make up the bone. Bones have several parts‚ but are manily made out of calcium deposits. It takes around 20 years for our bones to completely
