Question

in biological systems, the metal ions involved in electron transport are:??

Answer 1

Answer:

Electron transfer processes are mainly based on iron proteins, transport of oxygen requires iron and copper proteins, and zinc plays an important role in regulation of DNA transcription.

hope this answer is helpful for you.

Answer 2

Biological systems, the metal ions involved in electron transport are:

• Metal ions are essential for plants, animals, and people to live a long and healthy existence. Their important function in biological systems has long been acknowledged. They are required for life to exist, and their absence can result in growth problems, severe dysfunction, cancer, or death.

• Many of the enzymatic activities that power the body's metabolism require metals like iron, copper, and zinc to function properly. Ions like Fe2+, for example, can attach to haemoglobin and myoglobin proteins to assist deliver oxygen to the body's organs.

• They play a role in intracellular and intercellular communication, sustaining electrical charges and osmotic pressure, photosynthesis and electron transfer activities, nucleotide pairing, stacking, and stability, as well as DNA transcription control. They are essential for the normal functioning of nerve cells, muscle cells, the brain and heart, oxygen transport, and a variety of other biological functions, to the point that we can't picture existence without them.
