Explain where the enzymes for electron transport are located in bacteria (prokaryotes) if they don't have internal membranes, and therefore do not have a mitochondria

Answers

In bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.

Bacteria lack mitochondria, i.e. bacteria have no membrane-bound organelles.

In consequence, bacterial enzymes responsible for the electron transport chain are localized in the plasma membrane.

The electrochemical proton (H+) gradient required to create Adenosine triphosphate (ATP) from ADP and phosphate (Pi) is generated across the plasma bacterial membrane.

In bacteria, the electron transport chain is generally shorter and contains a lower phosphorus-oxygen ratio than the mitochondrial (eukaryotic) electron transport chain.

In conclusion, in bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.

What would most likely increase the genetic variation in a population of
organisms?

Answers

Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
