Answer:

A. play a role establishing and maintaining membrane lipid asymmetry

Explanation:

Proteins that move move certain phospholipids between leaflets are transmembrane proteins via "flip-flop" transition have also the possibility to maintain membrane lipid asymmetry. There are few types of such proteins:

  • flipases-move lipids from the exterior to the interior side of the membrane, energy required
  • flopases-move lipids in reverse comparing to flipases, energy required
  • scramblases-no energy required, bidirectional

Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).

lesya [120]

Answer:

Two processes were described in this question, hence, the location of the two processes are as follows:

synthesize energy-rich organic molecules- CHLOROPLAST

Break them down to extract energy- MITOCHONDRIA

Explanation:

Plant cells are unique cells capable of synthesizing their own food via a process called PHOTOSYNTHESIS. The process of photosynthesis, which occurs in an organnelle called CHLOROPLAST, synthesizes a sugar (glucose), which is an energy-rich organic molecules i.e. it stores energy in its chemical bonds.

However, to harness the usable form of energy stored in the chemical bonds of Glucose, the cells need to break down the glucose molecule. Plant cells break down glucose in a process called CELLULAR RESPIRATION in order to convert the stored energy in Glucose to a usable form called ATP. This extraction of ATP molecule needed for every life process of the plant cell is carried out in another organnelle called MITOCHONDRION.

Okay so i hope this help but i think its this:

1. chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section

2. light (either natural sunlight or artificial light, like from a light bulb)

3. carbon dioxide (CO2)(a gas found in the air; one of the gases people and animals breathe out when they exhale)

4. water (which the plant collects through its roots)

5. nutrients and minerals (which the plant collects from the soil through its roots)

Did researching for you so I hope this helped? :)
