Ca2+
Mg2+
Fe2+
Al3+
Answer is Right!
Answer is Wrong!
The correct answer is B. Mg2+.
Chlorophyll is a green pigment found in plants and algae. It is responsible for absorbing sunlight and using it to convert carbon dioxide and water into glucose and oxygen in a process called photosynthesis.
The magnesium atom in chlorophyll is located at the center of the chlorophyll molecule. It is surrounded by four nitrogen atoms from the porphyrin ring and four oxygen atoms from the four pyrrole rings. The magnesium atom is essential for the function of chlorophyll, as it provides a stable platform for the attachment of the other atoms in the molecule.
The other options are incorrect because they are not found in chlorophyll. Calcium (Ca2+)
is a mineral that is found in bones and teeth. Iron (Fe2+) is a mineral that is found in blood. Aluminum (Al3+) is a metal that is found in many different minerals.
