This is likely a mutant mouse (as synaptic clefts are typically 10 to 20 nm wide). Given that neurotransmitters act over short distances, this mouse may demonstrate delayed responses to stimuli, or no responses at all.
That’s the answer
Energy stored in food can be used by cells to add a phosphate group to ADP to make ATP. This cycling of ATP to ADP occurs in a metabolic process called cellular respiration. phosphate group breaks, and energy is released. ATP becomes ADP, and the cycle of storing and releasing energy continues until the cell dies.
