certain protein can only act as a catalyst if it is linked with the B vitamin biotin. This protein is called and biotin is its
Membranes are essential components of all cells.
- Briefly describe the structure of a eukaryotic plasma membrane, identifying at least two component macromolecules and describing what their basic function is within the membrane.
The plasma membrane protects the integrity of the interior of the cell by allowing certain substances in, while keeping other substances out.
- Summarize the manner in which small molecules are permitted to pass through the membrane ensuring you explain the difference between passive, facilitated, active, and coupled transport by comparing and contrasting them.
- Finally, explain the difference between endocytosis and exocytosis and provide an example of a molecule (remembering to state its function) that is transferred using this method.

Hello,
I would like to ask you one specific question - We need RNA polymerase to make a protein, but RNA polymerase is made up of proteins. So how does RNA polymerase, or its subunits, appear in the first place?
Given the general equation below of photosynthesis, encircle the raw material and product of the light - independent reaction (calvin cycle) stage of photosynthesis.
6CO2 + 6H20 + sunlight → C8H12O6 + 602
a. In a pea plant that breeds true for tall, what possible gametes can be produced? Use

c. What will be the genotype of F1 offspring from a cross between these two types?
d. Assuming that the allele for tall is dominant, what will be the phenotype of F1
offspring from a cross between these two types?
e. What will be the probable distribution of traits in the F2 generation?
