Question

1. Which of the following vitamins is synthesized byintestinal bacteria? (a) folate (b) biotin (c) cyanocobalamin (d) pantothenic acid ----> my guess is A... I want to check if this iscorrect 2. which of the following is a feature of the muscular actionsof digestion? (a) peristalsis begins 1st in the stomach upon the initiationof the swallowing reflex. (b) the colon has the thickest & strongest muscles of theGI organs to withstand the pressure of stool evacuation (c) the jejunum has a 3rd layer of diagonal muscles to enhancecontraction and relaxtion phases for enhanced digestion (d) segmentation in the intestines allows periodic squeezingalong its length, resulting in momentary reversal of the movementof intestinal contents 3. Which of the following minerals is least likely to bedeficient in anyone's diet? (a) iron (b) calcium (c) chromium (d) phosphorus 4. All of the following are features of stomach acidexcept: (a) its secretion is stimulated by ingestion of regularcoffee (b) its secretion is stimulated by ingestion of decaffeinatedcoffee (c) it destroys most of the bacteria entering the stomach fromfood ingestion (d) its potentially destructive action on stomach cells isprevented by the presence of bile. 5. Which of the following is a property of vitamin B-12? (a) it is efficiently recycled by the body (b) it is necessary for protection from pinpointhemorrhages (c) it requires attachment to fatty acids for transport in thecirculation (d) It is absorbed from the stomach with the aid of a specialbinding protein 6. In general, the protein quality of legumes would be mostimproved by the addition of a plant protein rich in: (a) lysine (b) tryptophan (c) methionine (d) glutamic acid Thank you very much in advance 1.
