As you learned, membranes impermeable to hydrogen ions are required for electron transfer phosphorylation. Membranes in mitochondria serve this purpose in eukaryotes. Bacteria do not have this organelle, but they do make ATP by electron transfer phosphorylation. How do you think
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
As you learned, membranes impermeable to hydrogen ions are required for
electron transfer phosphorylation. Membranes in mitochondria serve this purpose
in eukaryotes. Bacteria do not have this organelle, but they do make ATP by
electron transfer phosphorylation. How do you think they do it, given that they
have no mitochondria?
