Answer:
The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.
Explanation:
These molecules require the help of specific transport proteins which are embedded in the phospholipid bilayer. Transport may occur through facilitated transport or active transport.
Answer:
The answer is ELECTRON TRANSPORT CHAIN.
Explanation:
The electron transport chain are the series of proteins that carry electrons through the membrane of the mitochondria. Mitochondria are the power house of the cells, they are made up of two cell membranes, the electrons transport chain takes place in the inner cell membrane.
The transportation of electrons through the mitochondrial membrane is also called oxidative phosphorylation. During the process of oxidative phophorylation, the energy release is capture in form of proton gradient and this is used to produce ATP via the process of chemiosmosis.
