3.5 Photosynthesis. 4 min read • december 28, 2022. Caroline Koffke. Haseung Jun. Photosynthesis is a chemical process with the following equation: H2O + CO2 → C6H12O6 + O2. Both plants and photosynthetic bacteria are capable of this complex conversion process. The overall reaction is spurred by the energy from a photon of light striking a ...A. When a charge reaches a synapse, it causes the gated calcium proteins to open which allows calcium to come into the synapse. When calcium enters it stimulates the vesicles around the neurotransmitters to release (exocytosis) the neurotransmitters into the synapse.
