Document Summary
Prolonged, high blood pressure hypertension, risk factor of chd (coronary heart disease)! Risk factors associated with hypertension are stress, obesity, smoking, high intake of. Smooth muscle in artery wall thickens narrows lumen of the artery heart must beat faster contracts with greater force than normal. [exam] -blocker binds to receptor / receptor on heart (muscle cells) / adrenaline cannot bind / blood pressure falls because heart rate reduced/force of contraction reduced. Antibiotics harm pathogenic bacteria by: bacteriostatic antibiotics that are slowing down their growth rate, bactericidal antibiotics that kill pathogenic bacteria (in correct concentration) Narrow-spectrum antibiotics (e. g. penicillin) are only effective on a few pathogens. Wide-spectrum antibiotics (e. g. chloramphenicol) are effective on many pathogens. Prevent formation of bacterial proteins: by inhibiting dna transcription or mrna translation, bacteria are unable to synthesise proteins affects the metabolism of bacteria. B-lymphocytes are fused with tumour cells in laboratory cultures. They divide rapidly to form a clone of identical cells.
