Answer:
It is associated with a sliding clamp only on the leading strand.
Explanation:
DNA polymerase must exhibit higher processivity for an efficient DNA replication process. The processivity is imparted by some specific subunits such as the beta subunit of DNA polymerase III. These subunits form a sliding clamp to allow the DNA polymerase to add a large number of nucleotides to the primer before detaching from the template.
Four copies of beta subunits of DNA polymerase III form a donuts shaped structure around each template strand of DNA and serve as a clamp. Each pair of beta subunits associated with core DNA polymerase. The function of these sub-units is to slide along DNA as replication processed. The sliding clamp does not allow the dissociation of DNA polymerase frequently and allows efficient replication of both leading and lagging strands.

Answer:
by binding to an ion channel
Explanation:
The neurotransmitters are chemical messengers capable of transmitting a signal from a given nerve cell across biological junctions named 'synapses' to target cells such as, for example, other nerve cells (e.g., neurons). In the cell, the neurotransmitters are transported into internal vesicles that are fused with the cell membrane to release them in the synaptic cleft by the process of exocytosis. Subsequently, the neurotransmitters bind to cell receptors localized on the postsynaptic membrane and thus trigger responses in postsynaptic cells. For example, glutamate is a neurotransmitter capable of exciting nerve cells by binding to a transmitter-gated ion channel called N-methyl-D-aspartate (NMDA).
<span>The electron transport chain is, in essence , aseries of redox reactions that conclude cellular respiration. during these redox reactions, NAD+ is reduced,which then oxidizes an electron acceptor in the electron transport chain.</span>
