Answer:
Hyperpolarization
Explanation:
When the membrane potential becomes more negative than the resting potential, the membrane is hyperpolarized. Hyperpolarization is inhibitory in nature and decreases the ability of the neuron to generate a neural impulse. During signal transmission at a chemical synapse, binding of neurotransmitters to the receptors stimulates the opening of ligand-gated ion channels. The flow of ions changes the voltage across the membrane and may cause depolarization or hyperpolarization. For instance, the opening of Cl– or K+ channels causes hyperpolarization.
Answer:A culture or growth medium
Explanation: A culture or growth medium contains essential nutrients that aids in the growth of microorganisms. A culture medium can be in liquid form or solid form. It is very important to make sure that a culture or growth medium is sterile and free from any form of contamination. The main function and importance of a culture or growth medium is to ensure that microorganisms grow in a sterile environment that has all the major and essential nutrients required for their growth and to preserve them against any form of harm or contamination such that when these organisms are needed they can be used.
Based on the graphs shown, it is possible to conclude that enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature. Enzymes speed up chemical reactions.
Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy of these reactions.
An enzyme works more efficiently at optimum pH and temperature values, which are specific for each enzyme.
Enzymes are denatured by extreme pH and temperature values because out-of-range values break down the hydrogen bonds that form the tertiary structure of the enzyme.
