Biology Study Term 1 Organic Compounds: Water- Provides an environment for metabolic reactions The structure gives it a slightly positive and slightly negative charge giving it the ability to dissolve substances. Carbohydrates: The main function of carbohydrates is to provide an energy source Carbohydrates can also be used for structural units such a deoxyribose. Composed of Carbon‚ Oxygen and Hydrogen. Monosaccharaides: Composed of 3 to 7 carbons. Prefixes indicate the number of

BRITISH ANTI SLAVERY MOVEMENT The movement in Britain to end both the slave trade and slavery was a long drawn out affair which involved the efforts of key individuals and groups: Quakers Also known as the Society of Friends First campaigners against the slave trade and in 1727 passed a proposal against the trade Acted as a pressure group in the movement for the abolition of slavery. Their strategy was to win over public opinion by carrying the arguments for abolition into every home in Britain

Chapter 5 Notes The study of energy and its transformations is called thermodynamics. An aspect of thermodynamics that deals with the relationships between chemical reactions and energy changes involving heat is called thermochemistry. 5.1 The Nature of Energy Energy is defined as the capacity to do work or produce heat. Work is the energy used to cause an object with mass to move. Heat is the energy of an object that causes its temperature to increase. Kinetic and Potential Energy

Biology Notes - Ecology and Eco-Systems Environment It is everything that surrounds you. It includes all natural living and non-living things that are included within the environment. All living organisms depend on the natural environment they live in. A natural environment is very different to a man made environment because a man made environment is heavily influenced by people whereas a natural environment is effected by people by a very small amount.

Biology‚ 7e (Campbell) Chapter 17: From Gene to Protein Chapter Questions 1) Garrod hypothesized that "inborn errors of metabolism" such as alkaptonuria occur because A) genes dictate the production of specific enzymes‚ and affected individuals have genetic defects that cause them to lack certain enzymes. B) enzymes are made of DNA‚ and affected individuals lack DNA polymerase. C) many metabolic enzymes use DNA as a cofactor‚ and affected individuals have mutations that prevent their enzymes

Which is reabsorbed by the proximal convoluted tubule cells?Na+‚K+‚ amino acids. 5. Glucose is not normally found in the urine because it is reabsorbed by the tubule cells. 6. Filtration at the glomerulus is inversely related to capsular hydrostatic pressure. 7. Tubular of glucose and many other substances is a Tm limited active transport of Na+

Unit 5 Describe the two process by which hormones can cause certain genes to be turned on. (4) Any 2 from: - A hormone binds to a receptor in the cell surface membrane - Idea of the receptor causing (chemical) changes inside the cell - A (functional) {second messenger} activates an {enzyme/transcription factor/eq} Any 2 from: - Idea of a hormone entering the cell through the cell membrane - The hormone binds to a receptor - The {hormone-receptor complex/eq} acts as a transcription factor
