macromolecules? Carbohydrates (monosaccharides & polysaccharides)‚ lipids‚ proteins‚ & nucleic acids. 4) What is the original colour of iodine‚ and what colour does it turn in presence of starch and glycogen? Starch: yellow --> blue-black (amylase in starch reacts with iodine) Glycogen: yellow --> reddish-brown (due to the multi-branched component) 5) How do plants and animals store simple sugar glucose? In the form of polysaccharides. In plants‚ starch is the polysaccharide with glucose

Describe (P4) the role of energy in the body and explain (M1) the physiology of three named body system in relation to energy metabolism. Introduction I will try to describe the role of energy in the body and explain the physiology of three names body system in relation to energy metabolism. I will try explain where energy comes from‚ how the body uses energy‚ how many calories do we need‚ what is metabolism/catabolism and anabolism and also I will try explain cellular respiration aerobic/anaerobic

intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs.<br><br>The first step of digestion begins at the mouth‚ where the food enters the mouth. Saliva is secreted from the salivary glands. The saliva contains enzymes such as Ptyalin‚ which starts sugar digestion. The enzymes also provide lubrication to help in the chewing and swallowing of the food. The food then goes down the esophagus and into the stomach‚ where the next
