I’m assuming the six kingdoms of life, but yes they do have a very large purpose for providing characteristics to bacteria, animals, fungi, humans, etc.
The Krebs Cycle is involved in cell respiration and produces NADH and FADH2 for the electron transport chain. So your answer would be "<u>Release energy for making ADP</u>".
Answer:
The correct answer is synapse, electrical signals, neurotransmitters.
Explanation:
Neuron communicates with other neurons via action potentials and chemical neurotransmitters through the synapse.
Two neurons form a junction that is termed as a synapse, there an action potential that results in neuron A to release a neurotransmitter (chemical).
Synapses are thought of as the site of converting an electrical signal into a neurotransmitter release which is a chemical signal.
Thus, the correct answer is synapse, electrical signals, neurotransmitters.
