The reaction center contains special chlorophyll called Chlorophyll a.
The nervous system is primarily responsible for controlling the body's reaction to the outside world. It receives information from sensory organs, processes it, and initiates appropriate responses to maintain homeostasis. Hormones released by the endocrine system also play a role in regulating the body's response to external stimuli.
The brain is the control, and the whole reaction of a reflex arc starts with a stimulus, ie, touching a hot flame, the detector of this stimulus being the receptor. The electrical impulses travel through the sensory neuron to which it is then carried to the synapse (impulses reach the brain) the energy is then transferred across the synapse, to the relay neuron and then to the motor neuron, finally reaching the effector, (mainly muscle or gland) to move away the body part.
A stimulus or trigger initiates a response in an organism. This can be anything from a change in the environment, a hormone release, or a signal from the nervous system, leading to a specific reaction or behavior.
It tells how much the reaction rate is affected by concentrations.

The key factor that initiates a nuclear chain reaction is the presence of a neutron that can collide with and split a nucleus of a fissile material, such as uranium-235 or plutonium-239.

A catalyst is a substance that initiates or accelerates a reaction. The catalyst will vary depending on the reaction so it is not possible to give a definitive answer to the question.
Photoinduced means that a reaction or change is triggered by light. It typically refers to a process where light initiates a chemical reaction or alters the physical properties of a material.
In a nuclear fission reaction, a freely moving neutron undergoes neutron capture and initiates the nuclear fission of a fuel atom.
Faster transmission of impulses in white matter allows for quicker communication between different parts of the brain and body. This can result in faster reaction times, more coordinated movements, and efficient processing of information, all of which are beneficial for the organism's survival and functioning.
Igniting is the correct spelling.
