Supplying enough energy to support the many functions of the body at work and play is one of the chief functions of food. This energy comes from the fats, carbohydrates, and proteins in the food you eat. Without energy stored in our bodies- our bodies would not function. It is required for the molecules to move in and out of the cells, for breaking down large molecules and also foe building new ones. The role of energy in our body consists of the breakdown of large, complex molecules to the simplest form to release energy, this is called catabolism.
There are two different types of carbohydrate, simple carbohydrates (or sugars) and complex carbohydrates (starches and fibre). Proteins are a vital nutrient which us used by the body for growth and repair, it is very important for infants and children also individuals who are ill or injured. one characteristic of proteins is that they are made up of amino acids. They are complex molecules that can promote good health. Lipids are insoluble within water, they have high energy content and can be metabolized to release calories, but they have many other uses as well.
Therefore this substance needs to be removed from the body before it interferes with muscle contraction. Lactic acid is the limiting factor of this energy system. The acid is designed to build up and accumulate in the system. As exercise continues it diffuses through the blood and muscle tissues in the hope of impeding muscle contraction. This is what makes our working muscles stop because we feel an uncomfortable burning sensation in our muscles because the passageway of oxygen is being blocked by the lactic acid.
Hereditary Fructose Intolerance Enzymes are involved in processes such as the breakdown of fructose because they speed the process up. These reactions would be a lot slower without them or may not happen at all. They act as a catalyst. Fructose is used as a source of energy for our bodies. Enzymes are needed to breakdown this sugar into energy.
Compounds called proteins and phospholipids make up most of the cell membrane. The phospholipids make the basic bag. The proteins are found around the holes and help move molecules in and out of the cell. Cell Membrane A cell membrane of the cell. It gives the cell its shape, it is the outer covering of the cell made up from phospho-lipid-protein bi-layer, which allows the materials to enter and to exit.
Insulin is one of many hormones that helps the body turn the food we eat into energy. Also, insulin helps us store energy that we can use later. After we eat, insulin works by causing sugar (glucose) to go from the blood into our body's cells to make fat, sugar, and protein. When we need more energy between meals, insulin will help us use the fat, sugar, and protein that we have stored. Insulin is produced by our own insulin that is made in
The energy for this process is supplied by the hydrolysis of ATP using the enzyme ATPase and a specific protein channel in the membrane. Active transport is the movement of substances from where they are less concentrated to where they are more concentrated. It is undertaken by carrier proteins in cell membranes, which move specific molecules or ions against the concentration gradient using energy supplied by ATP. Cells have many adaptations to allow them to facilitate active transport; they may have carrier proteins in the cell surface membrane designed to transport particular molecules or ions or possess many mitochondria to supply the required ATP. Active transport requires energy in the form of ATP and protein carriers to move the molecules across the membrane.
P2: Describe the characteristics of nutrients and their benefit to the body. Answer: Characteristics of nutrients and their benefit to the body are carbohydrates, starch and non-starch polysaccharides, sugar substitutes and sugar. Carbohydrates are one of the main types of food. Sugar and starch are main types of carbohydrates these carbohydrates provide energy for the body. Liver breaks down carbohydrates into glucose which the body uses for sugar.
Introduction Aerobic cellular respiration is the basis of energy for most living organisms. Adenosine triphosphate (ATP) is the fuel utilized for life. ATP is manufactured in a series of reactions that begin in the cytoplasm of the cell where glucose by the process of glycolysis is converted to pyruvate molecules. Pyruvates are then converted through an oxidative process to create acetyl-CoA. Acetyl-CoA is transported within the cell to the mitochondrion, a specialized organelle where acetyl-CoA converts into ATP.
