Which of the following statements is the most likely explanation for plant withering due to leaky membranes in cold temperatures
podryga [215]

Answer:

C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.

Explanation:

Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.

In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.

Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.

Gnom [1K]

A parent with one non-functional copy of the gene is a carrier. Carriers for Cystic fibrosis will have no symptoms but they can pass the non-functioning gene on to their children.

<h3>What is cystic fibrosis?</h3>

Cystic fibrosis is a genetic disease and individual must inherit two non-functioning CF genes that is one from each parent to have CF. Both parents must have at least one copy of the defective gene and people who have only one copy of the defective CF gene are called carriers but they do not have the disease. Many couples who have a child with CF have no family history of cystic fibrosis

Cystic fibrosis affects cells that produce mucus, sweat, and digestive juices and also it causes these fluids to become thick and sticky. They block tubes, ducts, and passageways.

Symptoms include cough, repeated lung infections, inability to gain weight, and fatty stools. Treatments for this disease may ease symptoms and reduce complications.
