Answer:
The correct answer is C
Explanation:
Allosteric enzyme is an enzyme that has more than one active site on the surface of the enzyme. Generally, the binding to one of these active sites affects the affinity of the other active sites on the enzyme; this causes the enzyme not to follow the Michaelis-Menten's enzyme kinetics. Thus, <u>when the activity versus substrate is plotted on a graph, a sigmoidal curve shown instead of an hyperbolic curve (like other enzymes)</u>.
Answer:
a. neurotransmitters presynaptic >>>> 2. chemicals that are released into the synapse
b. neuron postsynaptic >>>> 3. integrating information
c. neuron dendrites postsynaptic >>>> 1. receiving information
d. neuron cell body >>>> 4. sending information
Explanation:
Neurons transmit nervous impulses. These cells are composed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli (information) from other cells, and an axon that is a long structure capable of conducting the electrochemical signals. Every neuron forms <em>connections with other neurons</em>. These connections are known as <em>synapsis</em>. As it happens in every synapsis between cells when a presynaptic neuron sends information, a neurotransmitter is released. This molecule is a chemical substance that travels through the synaptic cleft to the junctional area and binds to its receptors in the postsynaptic membrane. This binding produces a depolarization of the cell called an excitatory postsynaptic potential. An action potential is initiated and spreads to the rest of the membrane depolarizing it.
A. True
Plants are multicellular organisms that are most definitely living!
The name of the reaction is DEHYDRATION SYNTHESIS.
Dehydration synthesis involves the chemical combination of two amino acids; during the reaction dipeptide bond is formed and water is given off as a byproduct of the reaction. The removal of water is called dehydration.
Answer: soil tests are most useful during the growing season to monitor plant nutrient uptake.
