For each of the following items, state: "Gram " if it is seen in just Gram positive bacteria, "Gram -" if it is seen just in Gra

m negative bacteria, or "both" if it is seen in both Gram positive and Gram negative bacteria.
1) A cell wall that is made of peptidoglycan
2) A cytoplasmic membrane composed of phospholipids and protein
3) An outer membrane that includes lipopolysaccharide (LPS)
4) A thick cell wall that causes the bacteria to be purple in the Gram stain
5) Teichoic acids and lipoteichoic acids embedded in the cell wall
6) A thin cell wall that causes the bacteria to be red in the Gram stain

1) A cell wall that is made of peptidoglycan BOTH

2) A cytoplasmic membrane composed of phospholipids and protein BOTH

3) An outer membrane that includes lipopolysaccharide (LPS) GRAM-

4) A thick cell wall that causes the bacteria to be purple in the Gram stain  GRAM+

5) Teichoic acids and lipoteichoic acids embedded in the cell wall GRAM+

6) A thin cell wall that causes the bacteria to be red in the Gram stain GRAM-

Both of them have peptidoglycan layer in their cell wall, but the one in Gram + is thick (multilayered), while the one in Gram- is thin. This is the reason why the crystal violet dye retain in the walls of Gram + causing them to be purple (Gram – stay red). Gram- are more resistant against antibodies because of their impenetrable cell wall.

What is water’s role in the light reaction of photosynthesis?
notsponge [240]

The correct answer is - Its electrons are used to form NADPH.

On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH.
