Chloride ion (Cl-) concentrations are approximately 10x higher outside of cells than inside. Imagine you discovered a novel protein that is required in liver cells for transporting Cl- out of the cell up its concentration gradient, and further found that this protein only functions if the Na+/K+ ATPase is active. Which of the following might you reasonably conclude about the Cl- transport protein?A. It could be a Na+/Cl- symporterB. It could be a K+/Cl- symporterC. It could be a Cl- ATPaseD. It must be a Cl- channel

B. It could be a K+/Cl- symporter.

Explanation:

It could be a K+/Cl- symporter.

It is dependent on either the Na+ or the K+ gradient for its energy. Symport with Na+ would require co-transport into the cell (down the Na+ gradient), but our novel protein transports Cl- out of the cell.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
