Which would least likely be able to cross the phospholipid bilayer of the cell membrane answers?
ruslelena [56]

Answer;

-Large polar molecule are list likely to cross the phospholipid bilayer.

Explanation;

-A large polar molecule would be the least likely to passively diffuse through a plasma membrane without the help of a transport protein. Both its size and the hydrophobic interior of the membrane would restrict it.

-Only small uncharged molecules can diffuse freely through phospholipid bilayers. Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes.

-Ions and large polar molecules cannot pass through the lipid bilayer. But more specifically, whether a molecule can pass through the membrane depends on its size and its electrical nature.

Describe the structural or environmental change of your chosen macromolecule. Then predict the effect this change will have on t
Wewaii [24]

Answer:

Choosing protein as macromolecule.

Explanation:

The given environmental changes can lead to structural changes in protein as well:

pH - Several amino acids contain sidechains with practical gatherings that can promptly pick up or lose a proton. Changes in pH would prompt an adjustment in the charge of the amino acids, prompting charge-charge attraction or repilsion between non-interfacing amino parts.  

Temperature - High temperatures can prompt protein denaturation. Warmth can upset hydrogen bonding and hydrophobic interactions.  

Reduction or oxidation Environment - Some tertiary structure of protein folding is held by disulfide linkages. Reducing agent will lead to unfolding by introducing itself to break disulfide bonds.

Effect of these change: Sequence of amino acid and structure of protein molecule form determines function, any slight change to a protein's structure may result in the protein to become dysfunctional or produce different product.

<h2>Production of mitochondrion DNA  </h2>

Explanation:

  • The cell is not capable to complete reaction related to ATP production and electron transport.
  • This is because the electron transport chain and ATP production are combined with the association of protein in the inner membrane of mitochondrion DNA.
  • Mitochondria are the powerhouses of the cell. In all eukaryotes that don't rely upon photosynthesis, the mitochondria are the primary wellspring of adenosine triphosphate (ATP), the vitality rich intensify that drives central cell capacities.
  • These capacities incorporate power age (for instance, in muscle compression and cell division), the biosynthesis, collapsing and debasement of proteins, and the generation and control of membrane possibilities.
