<span>The
answer is facilitated diffusion. It requires no energy because the ions are
traveling down the concentration
gradient. Facilitated diffusion is important
for the regulation of ions in a cell. It also enables
ions to pass across the hydrophobic layer of the cell membrane composed
of phospholipids.</span>
For a reaction to occur, substrate particles need to collide with each other with enough force (To overcome activation energy), at the right orientation for a successful collision, causing a reaction to occur.
Enzyme catalysts are a type of protein that has a specific 3 dimensional conformation. They have specific reaction sites called active sites. Substrates collides with the enzyme and binds to the active site if it fits to the specific 3 dimensional conformation. This allows bonds to be either formed or broken for reactions to occur.
This process provides an alternative reaction pathway with lower activation energy to enable the rate of reaction to increase.
Is a process called chemosynthesis, microbes at the base of the foodchain convert chemicals from the vents into usable energy.
Robert Hooke was the first person to see a dead cell.
It would belong to Kingdom Plantae. aka It is a plant!
