5. The permease (transporter) allows glucose and Na into the cell requires ATP. True or False?
dem82 [27]

Answer: 5. False 6. False

Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.

When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.

The transport mechanism is carrier mediated it does not require energy.

Most proteins destined to enter the endoplasmic reticulum _________. Group of answer choices are transported across the membrane
Svetlanka [38]

Answer:

Begin to cross the membrane while still being synthesized-C

Explanation:

The Endoplasmic Reticulum is a part of the endomembrane system of the cell which is mostly reponsible for the synthesis and modification of proteins, although synthesis of lipids in plant and animal are carried out here

For more synthesis of proteins, it

needs to be further transported into the Rough endoplasmic reticulum- the designated site for secretion after synthesis of proteins.

Also it has been found out that when this proteins enter the Endoplasmic Reticulum, they start to cross the membrane while still being synthesized.

These are all hypothalamic hormones except
Paul [167]

Answer:

The correct answer is luteinizing hormone.

Explanation:

Hypothalamus has two sets of nerve cells that produce hormones. One set sends the hormones that are anti-diuretic hormone and oxytocin. ADH regulates or water in the bloodstream by reabsorption of water at the kidney and oxytocin helps in pregnancy and breastfeeding.

The other set produces hormones growth regulating, stress releasing and stimulating and inhibiting hormones are dopamine, corticotrophin-releasing hormone, growth hormone-releasing hormone, gonadotropin-releasing hormone, somatostatin, and thyrotropin-releasing hormone.

Luteinizing hormone is secreted by the pituitary gland. It is one of the main hormones that control the reproductive system.

Thus, the correct answer is luteinizing hormone.
