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.
Translation proceeds in three phases: Initiation: The ribosome assembles around the target mRNA. The first tRNA is attached at the start codon. Elongation: The tRNA transfers an amino acid to the tRNA corresponding to the next codon.
Answer: transporting substances in a cell
Why: In eukaryotic cells, endomembrane system refers to the set of membranes present inside the cytoplasm which form single functional and developmental unit. The membranes are either connected directly or indirectly and exchange material with the help of vesicle transport. The main function of this system is to modify, pack and transport the proteins and lipids in and out of the cell. The main organelles which form the endomembrane system are- nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles.
Through "cellular respiration" process energy is stored in the form of glucose.
<u>Answer:</u> Option A
<u>Explanation:</u>
The series of metabolic reactions and mechanism take place in organism ranging from microscopic bacteria to large organisms cells in order to transfer biochemical energy from food nutrients (stored in glucose form which is transferred) to adenosine triphosphate (ATP) and then waste product is also released, the whole process is known as "cellular respiration".
The energy required for ATP synthesis extracted from the breakdown of foods and phosphocreatine (creatine phosphate). It is stored inside muscle cells because phosphocreatine is readily available to produce ATP quickly.
