The shoots are generally cooked and then eaten either hot or cold. Asparagus contains several mineral ions that have important functions in the bodies of mammals. Complete Table 6.1 to summarise some of these functions.
When asparagus is digested, some of the compounds formed move rapidly through the body and produce a characteristic smell that only 22% of people can detect. In these people, the compounds attach to specific chemoreceptors in the nasal cavities. Complete the sentence below using the most suitable scientific term. The chemoreceptors will send impulses to the brain only if the ........................................ potential is reached.
Outline how molecules, such as the compounds from the digestion of asparagus, move from the blood to form part of the glomerular filtrate.
