The theory of endosymbiosis states that the eukaryotic cells evolved from the prokaryotic cells. According to this theory, a large bacterium ingested a small bacterium and then they evolved together working as a single unit. This can be shown through a model by demonstrating a big bacteria ingesting the small one. The small bacteria came to be cell organelles, such as mitochondria and chloroplasts in the eukaryotic cells with their own DNA.

Correct: show the big bacteria ingesting the small one

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.
