Question

Spectrin is a protein found in all eukaryotic cells that provide support to the plasma membrane. Transmembrane proteins allow large particles to pass through the membrane. Certain prokaryotes and eukaryotes adapt to changing environments by changing the unsaturated hydrocarbon tails of the plasma membrane. Animals, yeast, bacteria, and viruses contain membrane organelles Animals, yeast, bacteria contain a cell membrane organelles Reduction is gaining of H+ and oxidation is gaining of H+ Formation of macromolecules is an energetically favorable reaction that is coupled with formation of monomer, an energetically favorable reaction The breakdown of macromolecules is a spontaneous reaction Vmax is used to indicate if the substrate is binding very tightly to the enzyme. A high Vmax indicates weak binding and a low Vmax value indicates tight Activated carriers are large molecules that that contain one energy-rich covalent bonds

Explanation / Answer

Ans-41- true spectrin provide support to plasma membrane.

Ans-42 true transmembrane protein acts as gateway for a cell.

Ans-43true the arrangements of unsaturated hydrocarbon tails alter with change in environmental conditions.

Ans-44- true they have organelles like mitochondria, endoplasmic reticulum etc.

Ans-45- true they contain cell membrane known as capsule, capsid etc.

Ans-46-false bacause reduction is gaining of H+ while oxidation is loss of H+

Ans-47 true as in digestion the macromolecules are formed during formation of monomers from polymers.

Ans-48-false it is non spontaneous.

Ans-49false v max indicate the saturation of enzyme with substrate.

Ans-50-true one best example is ATP. These are energy rich.
