Enzymes and Their Importance in Plants and Animals Enzymes are large proteins that are responsible for catalysing thousands of metabolic processes that sustain life. Enzymes work similarly to those catalysts used in industry by lowering activation energy and therefore dramatically speeding up the rate of a reaction‚ however‚ these biological catalysts are highly selective to their substrate. Almost every chemical reaction that occurs in a cell requires enzymes in order to occur at rates required

BASIC CHEMISTRY 1. What is the difference between being ionized and being polar? When ionized the atom will either lose or gain electrons. A polarized molecule has an overall neutral charge with positive and negative sides such as H2O. 2. Compare macromolecules to Monomers; complete the chart below Example of a Macromolecule | Corresponding Monomer | polysaccharide | monosaccharide | lipids | glycerol‚ fatty acid | protein | Amino acids | nucleic acid | necleotides

Body’s Response to Acute Exercise Musculoskeletal response: There is an increase in blood supply as your body is working "overtime”. The blood supply has to increase because it has to go to the parts in your body which you are exercising the most e.g. If you are taking a run‚ the blood supply will increase because your legs will need more energy‚ therefore there will be more blood circulating your legs than normal because you are overworking them. Your muscles and all your body organs need

Callum Bourke Describe the long term effects of exercise on the Muskoskeletal system and energy systems. (P3) Describe the long term effects of exercise on the cardiovascular and respiratory systems. (P4) Cardiovascular System Cardiac Hypertrophy The heart increases in size and volume; this allows more blood to enter the heart allowing a greater amount of oxygenated blood to be pumped to the working muscles. To withstand the large amount of blood‚ the left ventricle becomes thicker

play a role”. (Association‚ Diagnosis and Classification of Diabetes Mellitus‚ 2010‚ pp. 562-569) Diabetes mellitus generally results from an insulin deficiency or resistance. Insulin transports sugar into cells for use as energy and storage as glycogen which is a carbohydrate. Insulin also stimulates protein synthesis and free fatty acid storage. Insulin deficiency or resistance compromises the bodies access to essential nutrients for fuel and storage. Several processes called pathogens(capable

Chapter 2 Chapter 2 is about Molecular level of life/ the chemical component of life. What does chemistry have to do with our life? Chemical aspect of life. Matter: anything in the universe that has weight and occupies space. The weight is called mass. The mass will remain constant regardless of gravity. Can exist in our body in three different forms Three states of matter in our body. * Solid: in our body are organs‚ Bones‚ they will have different shapes. * Liquid: In our body

Body in Action – Muscular System Roughly 40% of your body mass is made up of muscle‚ the key purpose of which is to move the bones of your body. In this assignment muscle movements and short and long term responses to exercise will be looked at. Types of Muscle Within the body‚ there are three different types of muscle. 1. Cardiac Muscle 2. Skeletal Muscle 3. Smooth Muscle Cardiac Muscle This is specialised muscle of the heart (BTEC National Sport Book 1). This is an involuntary type
