In adipose and skeletal muscle cells, insulin stimulates: <\/p>\n\n\n\n
1) active transport of glucose <\/p>\n\n\n\n
2) opening of chemically-gated channels <\/p>\n\n\n\n
3) entry of insulin into cells <\/p>\n\n\n\n
4) opening of glucose channels<\/p>\n\n\n\n
5) increased cell membrane glucose carriers<\/p>\n\n\n\n
The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n Correct Answer:<\/strong> Insulin plays a critical role in regulating blood glucose levels, especially after meals. In adipose (fat)<\/strong> and skeletal muscle<\/strong> cells, insulin promotes glucose uptake<\/strong> primarily by increasing the number of glucose transport proteins<\/strong> on the cell membrane.<\/p>\n\n\n\n These glucose transport proteins are known as GLUT4 transporters<\/strong>. Normally, GLUT4 resides inside the cell, stored in vesicles. When insulin binds to its receptor on the surface of adipose or muscle cells, it triggers a signal transduction pathway that causes these vesicles to move to the cell membrane and fuse with it. This process increases the number of glucose carriers<\/strong> (GLUT4 proteins) on the membrane, making it easier for glucose to enter the cell from the bloodstream.<\/p>\n\n\n\n The mechanism is not<\/strong> about:<\/p>\n\n\n\n Thus, insulin does not open a “channel”<\/strong> but rather increases the number of GLUT4 carriers<\/strong>, which work via facilitated diffusion<\/strong>, a passive process that depends on glucose concentration gradients.<\/p>\n\n\n\n This effect is essential in lowering blood glucose levels after meals and providing muscle and fat cells with glucose for energy production or fat synthesis. A failure in this mechanism, such as in Type 2 diabetes<\/strong>, results in poor glucose uptake despite normal or high insulin levels, often due to insulin resistance where cells fail to respond properly to insulin.<\/p>\n","protected":false},"excerpt":{"rendered":" In adipose and skeletal muscle cells, insulin stimulates: 1) active transport of glucose 2) opening of chemically-gated channels 3) entry of insulin into cells 4) opening of glucose channels 5) increased cell membrane glucose carriers The correct answer and explanation is: Correct Answer:5) increased cell membrane glucose carriers Explanation (300 words): Insulin plays a critical […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-26926","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/26926","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=26926"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/26926\/revisions"}],"predecessor-version":[{"id":26928,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/26926\/revisions\/26928"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=26926"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=26926"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=26926"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
