2 Section A Answer all questions in this section. You are advised to spend no more than 1 hour and 15 minutes on this section. 0 1 . 1 Describe how stimulation of a Pacinian corpuscle produces a generator potential. [3 marks] Scientists investigated the stimulation of a Pacinian corpuscle in the skin of a fingertip. The scientists applied two different pressures to the fingertip and recorded the changes in membrane potential of the Pacinian corpuscle’s sensory neurone. Figure 1 show...

AQA GCSE Biology Topic 5 Homeostatis Homeostasis The maintenance of a constant internal state in a changing environment Why is homeostasis important? Homeostasis is important because it is essential for the survival of cells and enzymes Automatic control systems are made up of Receptors, coordination centres, effectors negative feedback a mechanism of response in which a stimulus initiates reactions that reduce the stimulus Receptor Detects change Coordination centre Receives an...
