Describe an experiment you would perform to prove that an orange contains vitamin C
Tanya [424]
To prove that a certain fruit (in this case, an orange) indeed contains a certain compound (in this case, vitamin C); then the vitamin C should be extracted and isolated from the orange and must be confirmed by molecular analysis. The extraction process involves using chemicals (i.e. 6% MPA), and procedures such as centrifugation and filtration. Then the extract is stored and subjected to high-performance liquid analysis (HPLC) to measure the vitamin C content.

Sever21 [200]

Answer: D)

Membrane proteins produce phospholids

Explanation:

Membrane proteins in the mitochondria do more than just generate cellular energy. The proteins in the membranes of the mitochondria are complex machines in the nanoworld that mediate the oxygen-coupled generation of energy in cells. Their role in this process is not yet understood in detail.

Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
