Answer:
a. are acid participants in, or by-products of, cellular metabolism
Explanation:
cellular metabolism is the process in which several chemical recation stakes place in body. there aretwo type of cellular metabolism - catabolism and anabolsim, which serves for several body functions.
During the chemical reaction of cellular metabolism, many acids are produced which are called metabolic acids. Several metabolic pathways produces different acids such as carboxylic acid, citric acid and amino acid. All the metabolic acid maintains body's functional activities,if any case acid formation increases it causes metabloic acidosis.
Hence, the correct option is a. "Metabolic acids are the acid participants of celular metablosim".
Answer:
When an action potential reaches the end of an axon, the nervous terminal or the varicosities release neurotransmitters. These bind to receptors on the postsynaptic neuron. Eventually, the neurotransmitters are removed from the synapse. Some are reabsorbed by the presynaptic neuron or sending neuron, a process called reuptake, and some are broken down, in a process called enzymatic degradation.
Explanation:
Neurotransmitter liberation occurs from the nervous terminal or varicosities, in the neuronal axon. There are vesicles in the sending neuron that have neurotransmitters in their interior. When an <em>action potential reaches the nervous terminal</em> or the varicosities, it occurs a notable increase in the <em>neurotransmitter liberation</em> by exocytose. This is possible because calcium channels open letting the ion in the cell through the membrane, and letting the neurotransmitter out to the synaptic space. The molecule binds to its receptor in the postsynaptic neuron. This receptor is a <em>protein structure that triggers an answer</em>. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. <em>To stop this process</em>, the <em>neurotransmitter must be taken out from the synaptic space.</em> There are two mechanisms by which the neurotransmitter can be eliminated:
Enzymatic degradation/deactivation: In the synaptic space, there are <em>specific enzymes that can inactivate the neurotransmitter </em><em>by breaking it down or degrading it</em><em>.</em> In this case, the new molecule won’t be able to bind to the neurotransmitter receptor.
Reuptake: There are receptors located in the presynaptic membrane that can capture de molecule to store it back in new vesicles, for posterior use. These <em>transporters are active transport proteins</em> that easily recognize the neurotransmitter.
Answer:
the release of energy
Explanation:
the removal of phosphate group from ATP releases 7300 calories of energy to make it a ADP
Answer: Vascular tissue, production of sugar
Explanation:
After he ate, glucagon from the cookies increased his blood sugar levels
Insulin was secreted after he ate the cookies because his blood glucose was high.
