Modeling Photosynthesis and Cellular Respiration Teacher Information Summary Students use simple snap beads to model the reactants and products of photosynthesis and cellular respiration. Optional review cards are provided to help students distinguish between photosynthesis and cellular respiration. Core Concepts Photosynthesis, which occurs in
Botox (Botulin toxin) blocks release of ACh at NMJ â¢ Act at presynaptic receptors to block or stimulate neurotransmitter release o Adenosine acts at presynaptic receptors to inhibit/block release of excitatory amino acids (like glutamate)â¦effect is blocked by caffeine ï§ This is an example of disinhibition = removal of the inhibition Cholinergic ...
