Answer:
Enzymes are one kind of protein which functioning as catalyst that speed up reactions by lowering activation energy.Enzyme accelerate a reaction without altering its chemical equilibrium.
Explanation:
Energy which is required for start a biochemical reaction is called activation energy.Activation Energy helps to jump and start a thermodynamically favorable reactions.
Enzymes can many way to its activation energy.
1. The enzyme may hold the substrates in such a way as to distort the substrate bonds closer to their form in the transition state. This reduces the amount of energy needed to complete the transition.
2.Enzyme create a charge distributor which opposite of transition state his lowers the energy of the transition state and decreases the activation energy.
3.The enzyme may reduce the reaction entropy by bringing substrates together in the correct orientation to react.
4. The enzyme may provide a completely different chemical pathway for the reaction. It may form new bonds in the ES complex that would be difficult to form without the enzyme.
Answer:
3. the absence of a cell wall in human cells
Explanation:
Animal cells do not have cell walls. Cell membranes separate the cytoplasm of the animal cells from the surroundings and maintain their interior. Plant cells have cellulosic cell walls. A cell wall surrounds the cell membrane of a plant cell. Cell walls serve to provide structural support and protect plant cells from pathogens. Cell walls also help keep excess water out of cells so they do not burst. Therefore, human cheek cells would not have cell walls while the onion cells would have cell walls made up of cellulose.
Since enzymes function as organic catalysts, a cell would not be able achieve homeostasis if the required enzymes were not present.

Explanation:
Answer: One thing that is NOT true that concerns conifers is <u>they have motile sperm. </u>
Explanation:
Conifers are a seed plant. They are usually trees that bear cones and they have vascular tissues. They are classified as gymnosperms. The living confers are all woody plants.
The trees that are conifers are;
- Junipers
- Cedars
- Cypresses
- Firs
- Kauris
- Redwoods
- Spruces
- Yews
The colors of these conifers vary and include colors such as rainbow, bronze, yellow, blue, and red.
