Answer:

aquaporins

Explanation:

aquaporins are channel proteins that allow water to flow through a membrane. The rate of osmosis depends on ratio of intracellular to extracellular concentration as well as the presence of aquaporins in the cell membrane

20. Explain how health care professionals treat unregulated (or abnormal) cellular growth in the body
goldenfox [79]

Unregulated and uncontrolled cell growth is the most common simple definition of cancer. Because of the many types of cancers and a huge range of possible symptoms, treatments are also very diverse. Type of treatment also depends on cancer stage at diagnosis, and the patient's overall health. Some forms of treatment:

• Chemotherapy-usage of chemicals (medications) that target rapidly uncontrolled dividing cells,

• Hormone therapy

• Immunotherapy-usage of the medications that boost the immune system

• Radiation therapy-usage of radiation to kill the cancer cells

• Surgery

• New approaches such as stem cell therapy or personalized therapy.

The Citric acid cycle occurs in the mitochondria. There are nine biochemical reactions involved in the Citric acid cycle, and th
Sauron [17]

Answer:

. 2C- acetyl Co-A from the link reaction  enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6-  Citrate

The Citrate forms intermediate Isocitrate, which eventually formed  6-C alpha ketoglutarate.

The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed  5C-succinate.

5C -Succinate  forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.

The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid  from which other products are  formed from.

Which of the following genes would not likely be encoded on a plasmid?
raketka [301]

Answer:

gene encoding enzymes for glycolysis.

Explanation:

Plasmid may be defined as an extra chromosomal circular DNA that replicate independently of the main chromosomal material. Plasmid are generally used for the manipulation of genes in molecular technologies.

Plasmid can encode gene for toxins, antibacterial resistance and for the unusual substrate degradation. The plasmid cannot code enzyme for glycolysis because these enzymes are already present in the host organisms. Glycolysis enzymes are independent on the plasmid regulation.

Thus, the correct answer is option (3).
