Answer:
A protein with its amino-terminus in the cytoplasm and its carboxy-terminus in the extracellular space. (Ans. A)
Explanation:
Integral membrane protein (IMP) is defined as a membrane protein molecule which is directly attached to the biological membrane known as phospholipid bilayers. All transmembrane proteins are integral membrane protein but not all integral membrane protein are transmembrane proteins.
Integral membrane proteins function as a transporter, receptors, channels, proteins which is responsible for cell adhesion, proteins are also Involved in transduction and build up of energy.
Membrane proteins are class according to their transmembrane domain properties. The N-terminus of an integral membrane protein type I is in the endoplasmic reticulum lumen, where N-terminus of an integral membrane protein type II in the cytoplasm.
To find the surface area to volume ratio, we first need to find the surface area and the volume.
To find surface area, we just need to take the area of one of the faces and multiply that by 6 (since there are 6 faces on a cube).
We know that the length of one side is 3cm. To find the area of one face, we just need to multiply length * height. Since it's a cube, length and height will be the same.
3 * 3 = 9
The area of one face is 9. To find the surface area of the cube, we need to multiply the area of one face by 6.
9 * 6 = 54
The surface area of the cell is 54cm2.
Now to find volume.
The volume of a rectangular prism is simply length by width by height.
3 * 3 * 3 = 27
The volume of the cell is 27cm3
The surface area to volume ratio for this cubical cell is 54:27, or 2:1.
Hope this helped =)
I don't really get your question but i would have to guess that the temperature would have been colder since the sun wouldn't have been created yet (if your talking about before everything)
correct me if im wrong :P
Cytosine binds with guanine, therefore there will be the same percentage of guanine nucleotides as cytosine.
100-38-38 is 24% adenine and thymine
24/2=12%thymine
<span>Laocoön and his sons (Laocoon group) revealed changing Greek attitudes about the body during the Hellenistic period.
</span><span>Hellenistic period covers the period which </span>lasted from the death of Alexander in 323 B.C. until 31 B.C., when there was an emergence of Roman Empire. The word Hellenistic originated from the word Hellazein, the meaning of this word in English is to speak or to identify Greeks.
