AQA GCSE Biology-Metabolism

(0)
Designed for the new specification AQA GCSE course but can be modified for other exam boards. 17 slides covering Metabolism. By the end of the powerpoint students would have covered: 4.4.2.3 Metabolism Students should be able to explain the importance of sugars, amino acids, fatty acids and glycerol in the synthesis and breakdown of carbohydrates, proteins and lipids. Metabolism is the sum of all the reactions in a cell or the body. The energy transferred by respiration in cells is used by the organism for the continual enzyme controlled processes of metabolism that synthesise new molecules. Metabolism includes: conversion of glucose to starch, glycogen and cellulose the formation of lipid molecules from a molecule of glycerol and three molecules of fatty acids the use of glucose and nitrate ions to form amino acids which in turn are used to synthesise proteins respiration breakdown of excess proteins to form urea for excretion.

AQA GCSE Biology- The heart and blood vessels

AQA GCSE Biology- The heart and blood vessels

(0)
Designed for the new specification AQA GCSE course but can be modified for other exam boards. 23 slides covering the The heart and blood vessels. By the end of the powerpoint students would have covered: Students should know the structure and functioning of the human heart and lungs, including how lungs are adapted for gaseous exchange. The heart is an organ that pumps blood around the body in a double circulatory system. The right ventricle pumps blood to the lungs where gas exchange takes place. The left ventricle pumps blood around the rest of the body. Knowledge of the blood vessels associated with the heart is limited to the aorta, vena cava, pulmonary artery, pulmonary vein and coronary arteries. Knowledge of the names of the heart valves is not required. Knowledge of the lungs is restricted to the trachea, bronchi, alveoli and the capillary network surrounding the alveoli. The natural resting heart rate is controlled by a group of cells located in the right atrium that act as a pacemaker. Artificial pacemakers are electrical devices used to correct irregularities in the heart rate. The body contains three different types of blood vessel: • arteries • veins • capillaries. Students should be able to explain how the structure of these vessels relates to their functions. Students should be able to use simple compound measures such as rate and carry out rate calculations for blood flow.
