Postganglionic neurons of the sympathetic nervous system can be characterized as having which of the following receptor type?A. Muscarinic acetylcholine receptorsB. Nicotinic acetylcholine receptorsC. Adrenergic receptors
The receptor type is Adrenergic Receptors. As mentioned, neurons that produce and release the neurotransmitter NE are known as adrenergic neurons.
NE is secreted by postganglionic neurons of the sympathetic nervous system and binds to adrenergic receptors expressed on effector cells. Postganglionic neurons of the sympathetic nervous system use adrenergic receptors to respond to signals from the central nervous system. These receptors are activated by either epinephrine (adrenaline) or norepinephrine (noradrenaline) hormones. The hormones are released from the adrenal medulla and activate the postganglionic neurons to initiate the fight-or-flight response. The adrenergic receptors are divided into two major groups, alpha and beta. Alpha receptors are responsible for constriction of the blood vessels, bronchi, and other organs, while beta receptors are responsible for increased heart rate and contraction of the skeletal muscles.

Decussation on their way to cross over to the opposite side of the body, the axons of some trigeminothalamic pathway neurons synapse with second-order neurons here.
Second-order neurons make up these two nuclei (the dorsal column nuclei). The internal arcuate fibers, which comprise the medial lemniscus on each side, are the name given to their axons as they cross over to the other side of the medulla.
Sensory decussation is the term for this transition. So that they can switch sides, the axons of the neurons in each of these cortexes must bifurcate (split in two) at some point during their descent to the spinal cord.
This decussation or crossing takes place right before At the base of the brain, the nerve conveying the impulse does a U-turn and travels to the opposite side. The spinal cord receives the stimulation. The spinal cord's nerve fibers and a motor nerve share a synapse as the impulse travels there.

A sex-linked recessive condition, hemophilia. This means that whereas males can either be normal or affected, females can either be homozygous normal, heterozygous, or impacted by the condition. This is due to the fact that females have two X chromosomes (XX) while males only have one (XY). Additionally, males always inherit their X chromosomes from their mothers, whereas females inherit their Y chromosomes from their fathers. Therefore, if Irene's two X chromosomes are normal for hemophilia, none of her sons should be affected. All of her boys will have the problems if both X chromosomes are defective.

Which of the following processes do glycolysis link reaction citric acid cycle and electron transport chain belong to?
Glycolysis, the citric acid cycle, and the electron transport chain are three distinct metabolic pathways that work together to form cellular respiration. While the other two mechanisms are aerobic, glycolysis is anaerobic.
The process known as pyruvate oxidation is required in order to convert pyruvate molecules—a product of glycolysis—into the citric acid cycle. The first pathway in cellular respiration is glycolysis. This anaerobic route operates within the cell's cytoplasm. This process yields two pyruvate molecules and disintegrates one glucose molecule. Glycolysis consists of two halves, each with five stages. The "energy needing" steps are the ones in the first half.
This portion divides the glucose and consumes two ATP. The second half of glycolysis can start if pyruvate kinase levels are high enough. In the "energy releasing" stages in the second half, 4 ATP molecules and 2 NADH molecules are released. There is a net gain of 2 ATP and 2 NADH from glycolysis. Some cells (like mature mammalian red blood cells) are unable to respire aerobically, therefore their only source of ATP comes from glycolysis. However, most cells oxidize pyruvate before moving on to other cellular respiration pathways.

Active and passive transport are systems that are meant for transporting molecules through the cell membrane.
Active transport necessitates the movement of molecules, whereas passive transport does not necessitate the movement of molecules. Active transport involves molecules moving against a concentration gradient, whereas passive transport involves molecules moving along a concentration gradient.
There are three main active transport methods - ion pumps, exocytosis and endocytosis.
What is the main difference between active transport and passive transport?
There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
Four Main Kinds of Passive Transport are Found:

c. Draw a labeled diagram of an enzyme catalytic cycle that depicts the conversion of maltose into glucose. Be as detailed as you can.
d. Alpha-glycosidase is found in the saliva of most mammals. Suppose you were to ingest several saltine crackers (which are rich in starch) and then take a sip of lemonade (a solution which includes citric acid). How could the lemonade alter the efficacy of alpha-glycosidase?
Answer:
As a key enzyme regulating postprandial blood glucose, α-Glucosidase is considered to be an effective target for the treatment of diabetes mellitus. In this study, a simple, rapid, and effective method for enzyme inhibitors screening assay was established based on α-glucosidase catalyzes reactions in a personal glucose meter (PGM). α-glucosidase catalyzes the hydrolysis of maltose to produce glucose, which triggers the reduction of ferricyanide (K3[Fe(CN)6]) to ferrocyanide (K4[Fe(CN)6]) and generates the PGM detectable signals. When the α-glucosidase inhibitor (such as acarbose) is added, the yield of glucose and the readout of PGM decreased accordingly. This method can achieve the direct determination of α-glucosidase activity by the PGM as simple as the blood glucose tests. Under the optimal experimental conditions, the developed method was applied to evaluate the inhibitory activity of thirty-four small-molecule compounds and eighteen medicinal plants extracts on α-glucosidase. The results exhibit that lithospermic acid (52.5 ± 3.0%) and protocatechualdehyde (36.8 ± 2.8%) have higher inhibitory activity than that of positive control acarbose (31.5 ± 2.5%) at the same final concentration of 5.0 mM. Besides, the lemon extract has a good inhibitory effect on α-glucosidase with a percentage of inhibition of 43.3 ± 3.5%. Finally, the binding sites and modes of four active small-molecule compounds to α-glucosidase were investigated by molecular docking analysis. These results indicate that the PGM method is feasible to screening inhibitors from natural products with simple and rapid operations.

Fatty acids; chylomicrons C. Fatty acids: apolipoproteins D. Triacylglycerides; serum albumin E. Triacylglycerides; chylomicrons F. Acetyl-CoA
Dietary fat is absorbed through the intestinal endothelial cells and then transported in the lymph system in the form of triacyl glycerides bound to or part of chylomicrons
Because lipids, such as cholesterol and triglycerides, are insoluble in water these lipids must be carried in conjunction with proteins (lipoproteins) in the circulation. Large quantities of fatty acids from meals must be delivered as triglycerides to avoid toxicity. These lipoproteins are essential for the small intestine to absorb and transport dietary lipids, for lipids to travel from the liver to peripheral tissues, and for lipids to travel from peripheral tissues to the liver and intestine.
Hence, triacyl glyceride and chylomicron are two mode of lipid transport in intestine.
