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.

Answer:
Wallace Line
Explanation:
Wallace Line is a boundary line which is a transitional zone between Asia and Australia. This boundary drawn by the British naturalist Alfred Russel Wallace in 1859. This boundary restricts the transferring organisms such as flora and fauna from Australia to Asia. So that's why kangaroos, wombats, and koala bears are only present in Australia not in the continent of Asia.
For many species, there are often regional differences in their genes, although most of the time this differences aren't noticeable in their outward appearance.
The following statements apply to autotrophs only:
1. Make their own food.
2. Use inorganic materials to produce energy.
3. Producers.
4. Many use photosynthesis to produce organic compounds.
The following statements apply to heterotrophs only:
1. Consumers.
2.Rely on other organisms for energy.
3. Unable to produce organic compounds from inorganic materials.
4. Obtain their food by consuming other organisms.
Generally, autotrophs are plants, which are capable of trapping the energy of the sun to produce their own food. That is why they are called producers. They have the capacity to produce organic compounds using inorganic raw materials. Other living organisms depend on the foods produced by autotrophs. The heterotrophs do not have the capacity to produce their own foods so they depend on the food produce by autotrophs, they also feed on other living organisms. That is why they are called consumers. <span />
