This question is incomplete because the options are not given; here is the complete question:
Which one of the following processes does not occur to excess neurotransmitters in the synapse?
A. Break down or digested into inactive fragments.
B. Collection by scavenger vesicles left over from the neurotransmitter release.
C. Drifting away from the synapse via diffusion.
D. Reuptake within the pre-synaptic neuron.
The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.
Explanation:
The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.
Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.
I remember the secondary structure by visualizing it. Understand that primary structure is just the order of the amino acids. The tertiary structure is the 3dimensional configuration of the whole protein molecule with multiple interactions guiding its fold (disulfide bonds, ionic interactions, hydrogen bonds, van der walls). Secondary structure is a step towards the conformation of the protein where it is made up of either alpha-helices or beta-pleated sheets. The alpha helices look like a spiraling staircase while the beta-pleated sheets look like a repetition of long loops. These two structures hold itself by hydrogen bonds.
Answer: A zygote
Explanation:
a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
The correct answer would be A. All organisms are composed of multiple cells
