Answer the following question given this paragraph: The digestion of carbohydrates begins in the mouth as -amylase breaks glycosidic linkages in carbohydrate molecules. Essentially no carbohydrate digestion occurs in the stomach, and food particles pass through to the small intestine, where -amylase and intestinal enzymes convert complex carbohydrate molecules (starches) to monosaccharides. The monosaccharides then pass through the lining of the small intestine and into the bloodstream for transport to all body cells. Protein digestion begins in the stomach as pepsinogen in gastric juice is converted to pepsin, the enzyme that hydrolyzes peptide bonds. The partially digested protein then passes to the small intestine, where the remainder of protein digestion takes place through the action of several enzymes. The resulting amino acids cross the intestinal wall into the blood and are carried to the liver. Lipid digestion begins in the small intestine. Bile salts emulsify the lipid molecules, and then lipases hydrolyze them to fatty acids and monoglycerides. The hydrolysis products pass through the intestine and are repackaged for transport in the bloodstream. In cells that are operating aerobically, acetyl-CoA produced in stage II of catabolism is oxidized to carbon dioxide. The citric acid cycle describes this oxidation, which takes place with the formation of the coenzymes reduced nicotinamide adenine dinucleotide (NADH) and reduced flavin adenine dinucleotide (FADH2). The sequence of reactions needed to oxidize these coenzymes and transfer the resulting electrons to oxygen is called the electron transport chain, or the respiratory chain. The compounds responsible for this series of oxidation-reduction reactions include proteins known ascytochromes, FeS proteins, and other molecules that ultimately result in the reduction of molecular oxygen to water. Every time a compound with two carbon atoms is oxidized in the citric acid cycle, a respiratory chain compound accepts the electrons lost in the oxidation (and so is reduced) and then passes them on to the... Q: Protein digestion begins in the stomach as pepsinogen in gastric juice is converted to pepsin, the enzyme that hydrolyzes this? Choices: - disulfide bridges - hydrogen bonds - ionic bonds - peptide bonds A:
(Answer)
peptide bonds

Answer the following question given this paragraph: 31.3 Peripheral nervous system The peripheral nervous system is broken down into two sub-systems, the somatic nervous system and the autonomic nervous system. ANS - Autonomic Nervous System The ANS has two components - parasympathetic and sympathetic. The sympathetic nervous system is the "fight or flight" or fright response and results in an increased heart rate, increased rate of breathing, and an elevated blood glucose level. There is also decreased digestion. The second neurotransmitter is epinephrine. In this case, the first neuron is short and the second neuron is long. The parasympathetic nervous system is the rest and digest system. Drugs must be able to pass the blood brain barrier to have an effect on the CNS. Drugs act by affecting the neuron and how likely it is to fire an action potential. Stroke occurs when there is a blood clot that goes to the brain and prevent blood flow. Q: What are the two components of the autonomic nervous system? Choices: - empathetic and sympathetic - crystallisation and sympathetic - neurons and sympathetic - parasympathetic and sympathetic A:
(A).
parasympathetic and sympathetic
Ques:Answer the following question given this paragraph: Experimental controls are other factors that might affect the dependent variable. They are kept constant so they will not affect the results of the experiment. Q: In an experiment, what is kept constant so they will not affect the results, including affecting the dependent variable? Choices: - atmospheric controls - similar controls - educated controls - experimental controls A:

Ans:experimental controls
Ques: Answer the following question given this paragraph: A mitotic spindle forms from the centrioles and passes through the nuclear membrane, which remains intact. Chromosomes attach to the mitotic spindle, which separates the chromosomes and elongates the cell. Q: A mitotic spindle forms from the centrioles and passes through the nuclear membrane, which remains intact. chromosomes attach to the mitotic spindle, which separates the chromosomes and does what? Choices: - manipulates the cell - migrates the cell - destroys the cell - elongates the cell A:
Ans:
elongates the cell
