<span>The correct answer is b: Coenzyme A.</span>
During the process of pyruvate oxidation, acetyl CoA molecule is produced. Pyruvate oxidation is the link between glycolysis and Krebs cycle and it converts pyruvate (three-carbon molecule) into acetyl-CoA ( two-carbon molecule attached to Coenzyme A). NADH is produced and one CO2 released. AcetylCoA is the substrate for the next stage of cellular respiration, citric acid cycle.
Where are the questions cuz I don’t seem them either
Answer:
Prokaryotic cells include archaea and bacteria. They do not have membrane bound nucleus as well as most of the organelles
Answer:
The first stage of neural communication, <u>conduction</u>, is the movement of the signal within a single neuron. <u>Transmission</u> is the movement of a signal between neurons.
Explanation:
The neuron is the irreplaceable and highly specialized unit of the Nervous System, since it is the basic element in the conduction of the nerve impulse. The primary function of the neuron, conceived in its uniqueness, is to receive information and transmit it, once it has been processed.
The nerve impulse only spreads in one direction. When a neuron is stimulated, electrical changes originate that begin in the dendrites, pass through the neuronal body, and end in the axon, this is known as conduction. At the point where an axon and a dendrite are associated, it plays a very important role in the transmission of the impulse from one neuron to another and in the functioning and coordination of the nervous system in general, since the neurons do not act in isolation. The neurons are arranged in such a way that the axon endings of one are connected with the dendrites of the next neuron, but there is no physical contact itself, but a microscopic space that separates them, in addition there is a neurotransmitter substance that allows the flow of nerve impulse under those conditions, said substance is acetylcholine. These transmitting molecules diffuse through the synaptic cleft and chemically transfer the signal, from the axon of a neuron to the receptor neuron.
Answer: a niche is a role that an organism plays in an environment. If you want a dictionary definition, here it is.
Explanation:
a position or role taken by a kind of organism within its community. Such a position may be occupied by different organisms in different localities, e.g., antelopes in Africa and kangaroos in Australia
