Diffusion is one of the ways molecules/substances move or is transported. It is the process whereby substances move from a region of higher concentration to a region of lower concentration until there is an even distribution. Movement via diffusion occurs down a concentration gradient i.e high to low.
Since diffusion occurs down a concentration gradient, which is difference in concentration of a substance, it requires no energy in form of ATP to occur. This kind of transport which requires no energy input is called PASSIVE TRANSPORT, in contrast to active transport which requires.
Relative age only tells us the order in which events occurred, from the earliest to the most recent. Knowing the actual date of an event allows us to say exactly how old something is or how long ago it actually took place.
The cell is not capable to complete reaction related to ATP production and electron transport.
This is because the electron transport chain and ATP production are combined with the association of protein in the inner membrane of mitochondrion DNA.
Mitochondria are the powerhouses of the cell. In all eukaryotes that don't rely upon photosynthesis, the mitochondria are the primary wellspring of adenosine triphosphate (ATP), the vitality rich intensify that drives central cell capacities.
These capacities incorporate power age (for instance, in muscle compression and cell division), the biosynthesis, collapsing and debasement of proteins, and the generation and control of membrane possibilities.
