An action potential triggers the release of synaptic vesicles into the synaptic cleft by _____ channels, allowing _____ ions to

noname [10]

Answer:

1. opening Voltage gated channels

2. Calcium

Explanation:

The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.

The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.

The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.

Thus, opening Voltage gated channels and Calcium is the correct answer.

6. What is the relationship between an organism's DNA and protein specificity?

Svetach [21]

Answer:

The relationship between an organism's DNA and protein specificity is that DNA determines the amino acid sequence of each protein (option D).

Explanation:

Each organism's DNA molecule is formed by a specific sequence of nitrogenous bases that not only determine the amino acids that a synthesized protein will have, but also the order in which these amino acids will form the protein structure.

The steps in which this occurs can be summarized as follows:

The sequence of nitrogenous bases of a DNA strand is transcribed into the mRNA, which will go into the cytoplasm.
The sequence of bases in the mRNA is organized into triplets of bases, called codons, each of which encodes a specific amino acid.
During translation, each codon will indicate the amino acid that will be coupled to a protein molecule in a specific order.

According to this, the DNA determines the amino acids sequence that will be in a specific protein molecule.
