Lipids in a bilayer can diffuse laterally at a relatively fast rate, but "flip‑flop" from one leaflet to the other very slowly w

ithout catalysis. Three protein families, flippases (or flipases), floppases, and scramblases, catalyze the movement of lipids across the bilayer. Classify each phrase as describing flippases, floppases, or scramblases.

Answer:

Flippase, floppase and scramblases are transport protein that helps in the movement of lipid molecules between the two leaflets of the Phospholipid bilayer of the plasma membrane.

Explanation:

Flippases

They are the trans membrane protein that helps in the transport of lipid molecules from the extracellular region to the cytoplasmic region.Flippases belong to ATP binding cassette (ABC) transporter protein family.

Floppases

They also act as lipid transporter which helps in the movement of lipid from cytoplasmic region to the extracellular region of the phospholipid bilayer.

Scramblases

These proteins help in the movement of lipid molecules between the two leaflet of the lipid bilayer of the plasma membrane.Scramblase with its catalytic activity helps in the transport of negative charged phospholipid such as phosphotidly ethanolamine from the inner leaflet to the outer leafet and viceversa.

Choose the true statement(s) that support(s) the endosymbiotic theory. To be marked correct, you'll need to select all true stat
horsena [70]

Answer:

a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.

c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.

d.Mitochondria and chloroplasts replicate by a process similar to mitosis.

Explanation:

Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.

The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.
