Question

During cell respiration, the reactants of glucose and oxygen are transformed into the products of carbon dioxide, water, and ATP. Which of the following cell transport processes would be relatively unaffected if a cell no longer had access to glucose? Choose 1 answer: Choose 1 answer: (Choice A) A The transport of calcium into a muscle cell via facilitated diffusion. (Choice B) B The transport of an amino acid into an intestinal cell from an area of low concentration to an area of high concentration gradient. (Choice C) C The transport of sodium against its concentration gradient in a brain cell. (Choice D) D The passive transport of a charged potassium ion (K^+ + start superscript, plus, end superscript) through a cell membrane.

Answer 1

During cell respiration, the transport of calcium into a muscle cell via facilitated diffusion would be relatively unaffected if a cell no longer had access to glucose.

Step-by-step explanation:

During cell respiration, the reactants of glucose and oxygen are transformed into the products of carbon dioxide, water, and ATP. If a cell no longer had access to glucose, the cell transport process that would be relatively unaffected is the transport of calcium into a muscle cell via facilitated diffusion (Choice A). This process does not require glucose and is not directly involved in the production of ATP.

On the other hand, the transport of an amino acid into an intestinal cell from an area of low concentration to an area of high concentration gradient (Choice B), the transport of sodium against its concentration gradient in a brain cell (Choice C), and the passive transport of a charged potassium ion through a cell membrane (Choice D) all require energy and are directly involved in cellular processes that depend on the production of ATP through cell respiration.
