AQA AS Completion Sheet Section 1 Biological Molecules

AQA AS Completion Sheet Section 1 Biological Molecules

An AQA AS Biology Revision resource for Section 1 Biological Molecules. The worksheet covers two sides of A4 and is closely matched to the specification. The students fill in the gaps to complete the sheet. A full set of answers is given on the last 2 pages. I ask students to have their specification alongside as they complete the sheet so that they familiarise themselves with its content. Once completed it forms a useful revision summary sheet for the day before the exam. It is appropriate for both AS and A2 students.

Diffusion

Diffusion

This lesson is designed for the new AQA (9-1) GCSE. It includes a full PowerPoint presentation which goes through diffusion with interactive visuals and then gives examples of diffusion in nature. I combined the lesson with an aerosol demonstration and a potassium permanganate practical but there are lots of different ways to do it including a full investigation if you wanted to. This lesson also incudes a homework activity which includes a 6-mark question about the factors that affect the rate of diffusion and comes with an information sheet containing text and graphs. This homework could be used in class or could easily be adapted into various other activities.

Coordinated responses [REVISION NOTES]

Coordinated responses [REVISION NOTES]

Extract from notes: "Sympathetic nervous system sends out impulses to glands + smooth muscles  tells adrenal medulla to release ADRENALINE and NORADRENALINE into bloodstream  cause changes in the body (e.g. increased heart rate)Hypothalamus stimulated the pituitary gland to secrete adrenocorticotropic hormone (ACTH)  travels in blood stream to adrenal cortex  activates may hormones (prepare body for threats)"

Hormonal Communication [REVISION NOTES]

Hormonal Communication [REVISION NOTES]

Extract from notes: "Adrenal Cortex – outer region of the glands; Produces hormones vital for life; controlled by hormones from the pituitary gland - Types of hormones produced by the adrenal cortex:- Glucocorticoids: Cortisol – regulate metabolism of carbohydrate and proteins in the liver, blood pressure and cardiovascular function in response to stress; Glucocorticoid – regulate immune response; suppress inflammatory reactions- Mineralocorticoids: Aldosterone (maintains water balance between salt and water concentrations in the blood)- Androgens: Small amounts of male and female sex hormones; important in women after menopause"

Structure & Function of the Pancreas [REVISION NOTES]

Structure & Function of the Pancreas [REVISION NOTES]

Extract from notes: "ROLE AS AN EXOCRINE GLAND- Mostly made of exocrine glandular tissue – produce digestive enzymes and pancreatic juice (an alkaline fluid)  both are secreted into ducts  leads to the PANCREATIC DUCT  released into the duodenumDigestive enzymes the pancreas produces:- Amylases: break down starch into simple sugars (e.g. Pancreatic amylase)- Proteases: break down proteins into amino acids (e.g. Trypsin) - Lipases: break down lipids into fatty acids and glycerol (e.g. Pancreatic lipase)"

Diabetes Mellitus and its control [REVISION NOTES]

Diabetes Mellitus and its control [REVISION NOTES]

Extract from notes: "TYPE 1 DIABETES – inability to produce insulin- Unable to produce insulin- Beta cells in the islets of Langerhans do not produce insulin- Can’t be cured/prevented- Autoimmune disease: body’s own immune system attacks the beta cells- Begins in childhoodTYPE 2 DIABETES – insulin resistance- Person’s beta cells do not produce enough insulin OR - Person’s body cells do not respond properly to insulin (the glycoprotein insulin receptors on their C.S.M don’t work properly)  body cells lose their responsiveness to insulin  do not take up enough glucose, leaving it in the bloodstream- Due to excess body weight, physical inactivity, habitual eating of refined carbohydrates - Begins 50+ years"

Regulation of Blood Glucose [REVISION NOTES]

Regulation of Blood Glucose [REVISION NOTES]

Extract from notes: "Normal blood conc. = 90 mg cm-3INCREASING BLOOD GLUCOSE CONC.- DIET: eating carbohydrate-rich foods (pasta and rice)  they are broken down in the digestive system, releasing glucose  absorbed into the bloodstream  conc. rises- GLYCOGENOLYSIS: glycogen stored in liver + muscle cells broken down into glucose  released into bloodstream - GLUCONEOGENESIS: production of glucose from non – carbohydrate sources; (Liver can make glucose from glycerol and amino acids)  released into the bloodstream DECREASING BLOOD GLUCOSE CONC. - RESPIRATION: glucose in the blood used by cells to release energy; higher the level of physical activity  higher the demand for glucose (for muscles to contract)  greater decreases of blood glucose conc. - GLYCOGENESIS: production of glycogen; excess glucose is converted into glycogen  stored in the liver"
