Cellular respiration involves a series of chemical
reactions. The enzymes increase the rate of the reactions. So option “B” is the
correct option as far as the given question is concerned. The reactions that
are catalysed by enzymes actually helps the organism to grow, respond to
various changes in the environment, reproduce and continue maintaining their
own structures. Cellular respiration is also considered a part of the
metabolism process. This process actually helps in carrying the oxygen through
the blood.
Hi :) Hope this helps!
Bethanechol [Urecholine]
Bethanechol [Urecholine] is given orally for treating glaucoma. Direct-acting cholinergic drugs such as carbachol [Carboptic] are also used to treat increased intraocular pressure in conditions such as glaucoma and have positive effects when administered topically in the form of eye drops but are poorly absorbed when administered orally. Pilocarpine [Salagen, Pilocar] also has poor absorption capacity when administered orally for the treatment of intraocular pressure. However, it can be used orally for treating dry mouth (xerostomia). Drugs such as donepezil [Aricept] and galantamine [Razadyne] are indirect-acting drugs and are mostly used to treat neurological disorders such as Alzheimer's disease.
It is a vestigial Structure.
Explanation:
Answer: i think it's A or C i hope it's right
Explanation: Scientists are hunting for the insects, whose queens can grow to two inches long, in hopes of rounding them up before they become rooted in the United States and destroy bee populations that are crucial to crop pollination. The hornets launch most of their attacks on bees in the late summer and early fall.
To activate the kinases, cyclins connect to them. The activity of cyclin-dependent kinases changes with cyclin concentration. At the G2 phase, Cyclin and a Cdk unite to start mitosis (M phase). This mixture produces MPF (maturation-promoting factor), which encourages the cell to continue mitosis through the M phase. The cyclin is broken down at the G1 phase, and the Cdk is recycled.
<h3>What about cyclins?</h3>
- A family of regulatory proteins known as cyclins manages how the cell cycle develops.
- Cyclins cause the phosphorylation of cyclin dependent kinases (CDKs), which regulate the cell cycle.
- A target protein will attach to a complex made up of a cyclin and a CDK, and the complex will phosphorylate the protein.
- Cyclins collaborate with an enzyme family known as the cyclin-dependent kinases to control the cell cycle's activities (Cdks).
- A Cdk that is not bound to a cyclin is inactive, but when it is, it becomes a functioning enzyme that can alter target proteins.
- By phosphorylating and inactivating target substrates, cyclins are the regulatory subunits of holoenzyme CDK complexes that control progression through cell-cycle checkpoints.
- Cyclin-dependent kinases (CDKs) are protein kinases that require a distinct subunit - a cyclin - that provides domains necessary for enzymatic action.
- The cyclins associate with various CDKs to offer specificity of function at various stages during the cell cycle.
- In response to various extracellular and intracellular signals, CDKs modify transcription and play significant roles in the regulation of cell division.
