Can a protein that is not part of the cell membrane diffuse through the membrane? If not, why?
Katyanochek1 [597]

Answer:

Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane. Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. ... Channel proteins form open pores through the membrane, allowing the free passage of any molecule of the appropriate size.t is the proteins, therefore, that give each type of membrane in the cell its ... Many extend through the lipid bilayer, with part of their mass on either side ..... Many hydrophobic membrane proteins can be solubilized and then purified in an active, if not entirely ..... Many Membrane Proteins Diffuse in the Plane of the Membrane.

hope this helps :)

A population of 150 individuals has an allele frequency of 0.2 for the dominant allele (H) and a frequency of 0.8 for the recess
Amanda [17]
Hardy-Weinberg Equation (HW) states that following certain biological tenets or requirements, the total frequency of all homozygous dominant alleles (p) and the total frequency of all homozygous recessive alleles (q) for a gene, account for the total # of alleles for that gene in that HW population, which is 100% or 1.00 as a decimel. So in short: p + q = 1, and additionally (p+q)^2 = 1^2, or 1
So (p+q)(p+q) algebraically works out to p^2 + 2pq + q^2 = 1, where p^2 = genotype frequency of homozygous dominant individuals, 2pq = genotype frequency of heterozygous individuals, and q^2 = genotype frequency of homozygous recessive individuals.
The problem states that Ptotal = 150 individuals, H frequency (p) = 0.2, and h frequency (q) = 0.8.
So homozygous dominant individuals (HH) = p^2 = (0.2)^2 = 0.04 or 4% of 150 --> 6 people
Heterozygous individuals (Hh) = 2pq = 2(0.2)(0.8) = 0.32 or 32% of 150
--> 48 people
And homozygous recessive individuals (hh) = q^2 = (0.8)^2 = 0.64 = 64% of 150 --> 96 people
Hope that helps you to understand how to solve these types of population genetics problems!

The chemical energy of these plants all started with what energy source?
Zielflug [23.3K]

Answer:

Sun(solar energy)

Explanation:

The sun is the ultimate source of energy in our solar system.

The chemical energy in plants all started out with solar energy from the sun.

During the process of photosynthesis;

  • green plants manufactures their food using sunlight.
  • in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.

Photosynthetic reaction simply converts solar energy from the sun into chemical energy.

Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.

Describe structural changes that can occur to a protein after translation is make it function properly
AVprozaik [17]
The structural variations that can happen in a protein after translation to make it function appropriately are:

• Folding – In the cytoplasm it partakes chaperonin protein that will aid to fold the protein into a purposeful shape. The hydrogen bonds will form to create secondary protein and disulfide bonds will form tertiary structure and hydrogen bonds. 

• Cleavage – The activation into a purposeful protein over cleavage of certain amino acid sequences in which the amino acid order can fold to form the secondary or tertiary structure.

• Chemical Modification – A method of chemically responding a protein or nucleic acid with chemical components. 

• Elaboration – In particulars of folding, chaperones, kinds of bonds, the role of Golgi, combination into current molecular arrays. Etc.
