Biology Exam Revision Cells Cell Membrane The cell membrane surrounds the cytoplasm of a cell, separating its contents from the environment around it. The cell surface membrane consists of two layers of phospholipids and regulates what can enter and leave the cell. It is a semi-permeable membrane embedded with proteins, including receptors on the outer surface. Nucleus The nucleus is the.
The speed with which an action potential travels is increased by the presence of the Schwann cells that form a myelin sheath. These cells only allow for changes in membrane polarity at nodes of ranvier. Different neurons interact at synapses, where neurotransmitters such as acetocholine are released to continue the passage of an action potential. Sensory neurons receive outside stimuli, which.
Action potential depolarizes the presynaptic membrane 4. Ion channel opens to allow particular ion to enter cell 5. Synaptic vesicles release neurotransmitter into the synaptic cleft A) 4-3-1-2-5 B) 2-3-5-4-1 C) 1-2-3-4-5 D) 3-2-5-1-4. Version A 3 5. Acetylcholine, a common neurotransmitter, is synthesized in the pre-synaptic end of a neuron and released into the synaptic cleft as shown in the.

AP Biology Course Planning and Pacing Guide 3 (. The AP Biology exam has two large essays and six short answer questions that make up 50% of your score. For example, if a question asks you to describe mutualism, the grader is going to look for a definition of mutualism to award a point, and then an elaboration of mutualism, like an example, to give an additional point. People will think you.
