Neurotransmitters can affect postsynaptic cells by I) initiating signal transduction pathways in the cells II) causing molecular
Yakvenalex [24]

Neurotransmitters can affect postsynaptic cells by causing molecular changes in the cells.

The term "chemical messengers of the body" is frequently used to describe neurotransmitters. The nervous system uses these molecules to send information between neurons or from neurons to muscles. A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.

When a stimulus is potent enough, the chemical messenger neurotransmitter is transferred into the nerve impulse. If it is powerful enough, it will reach the postsynaptic cell and affect the structure of the neuron. And when signal transduction happens, everything mentioned above is completed.

The first stage of cellular respiration glycolysis is an anaerobic process. During glycolysis glucose is converted to two molecu
Oduvanchick [21]

Answer:

Oxidation of NADH by electron transport chain ensures a continuous supply of NAD+ for glycolysis.  

Explanation:

To continue the process of glycolysis, cells must have a continuous supply of NAD+ which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.

Which one of the following is a requirement for a good primer? Select one: a. Guanine and Cytosine should make up less than half
Alex

Answer: B. Melting temperatures of primer should be between 55-80 degree Celsius.

Explanation:

Bacause the melting temperature controls the binding of the primers to your template DNA. At melting temperature 50% of the primer molecules are bound to their corresponding target sequence. If the difference in melting temperature between the two primers is too high, it might be difficult to find experimental conditions where both primers can bind to their target.
