What is metabolism? All living things must have an unceasing supply of energy and matter. The transformation of this energy and matter within the body is called metabolism. Metabolism includes two different types: catabolism and anabolism. Catabolism is destructive metabolism. Typically‚ in catabolism‚ larger organic molecules are broken down into smaller constituents. This usually occurs with the release of energy. Anabolism is constructive metabolism. Typically‚ in anabolism‚ small precursor

getting rid of waste‚ but consuming proteins from vegetables or fish can be a healthier alternative. Also if you consume too much protein it will be converted to glucose or ketone bodies and if the body is low on energy demand it will be stored as glycogen and fat‚ which will cause weight gain (Pesta and Varman 3). Diets high in protein such as the Whole 30 have many benefits when it comes to weight loss people must be aware of the effects that it may cause in the

Chapter 3 The Body I. The cell The cell is the basic unit of life in our bodies. It has many “little organs” in them called organelles. Organelles have very specific functions. One example of an organelle is the mitochondria. Cells require nutrients and get rid of waste and live and die- just like us. II. Tissues‚ organs‚ organ systems Cells group together and form _____________________________ Some examples are: Tissues group together and form

homeostasis of calcium levels in the blood. 16. Insulin and glucagon help to keep the level of glucose in the blood stable. Insulin stimulates cells in the liver and muscles to remove sugar from the blood and store it as glycogen or fat. Glucagon stimulates the liver to break down glycogen and release glucose back into the blood. It also stimulates the release of fatty acids from stored fats. 17. The sodium-potassium pump in the neuron cell membrane uses the energy of ATP to pump Na+ out of the cell and

types of fuels involved‚ namely carbohydrates and lipids. Carbohydrates‚ which have the empirical formula (CH2O)n‚ acts as the predominant source of metabolic energy in muscle cells during exercise. They are stored in the liver and muscle cells as glycogen which is a branched polymer. Lipids mainly exist as triglycerides‚ which are made up of three fatty acids joined to one glycerol molecule‚ and are stored in adipose tissue. However‚ lipids exist as ketone bodies when in excess.

How long this energy supply lasts depends on the length and intensity of exercise and can range anywhere from 30 to 90 minutes or more. To avoid running out of energy during exercise‚ start with full glycogen stores‚ replenish them during exercise and refill them after exercise to be ready for the next

What are the central ideas of Cells? • What are cells? – Cells are the smallest basic unit of living things. • What do they do? – Cells take in raw materials and making new substances. • Why do they do this? – In cells‚ organelles carry out activities to keep the organism alive. – E.g. synthesising proteins and fats‚ releasing energy from glucose. What are the central ideas of Movement of Substances? • What processes describe how substances move from one region to another? –
