Question

Many prokaryotic cells can metabolize starch but it is too large to pass through the plasma membrane. How does a cell ultimately keep the monosaccharide inside the cell for further metabolism?

		amylase enzyme
		group translocation
		diffusion
		pinocytosis
		facilitated diffusion

You have isolated a motile, gram-positive cell with no visible nucleus. You can assume that this cell has

		mitochondria.
		ribosomes.
		all of the choices are correct.
		an endoplasmic reticulum.
		a Golgi complex.

Answer 1

Answer - correct option is amylase enzyme.

Explaination -

Bacteria show extracellular digestion. They are heterotrophs and living on dear organic matter. However they break down the complex food by secreting varios digestive enzymes into the environment. Then absorbed the simplified product into their body for further metabolism i.e for generation of energy.

Answer - correct option is ribosome.

Explanation - In any bacteria whether it is gram positive or gram negative bacteria, all are prokaryotes. They don't have any double membrane bound organelles like mitochondria, endoplasmic reticulum(ER), Golgi complex and nucleus as well. However single membrane bound organelles like ribosome, vacuoles and lysosomes are present.

Here it's is a gram positive bacteria so it doesnot have any cell organelles i.e Golgi complex or endoplasmic reticulum but it must contain 70S ribosomes.
