False..... pollination occurs at stigma not ovary !!!
The first answer Is A and the second answer is also A
A change in the order of amino acids can completely change the entire structure of the protein.
The shape of the protein is the result of how amino acids react to each other and the environment. Amino acids are all very similar in structure, but each has an individual R group that has its own properties, such as polar, non polar, able to form disulphide bonds, etc. that dictates how it will interact (ex. non polar AAs will be on the inside of the protein while polar will be on the outside, two AAs that like to form disulphide bonds will gravitate toward each other).
<em />If one of these amino acids is misplaced, the protein is likely to be shaped a completely different way which often hinders its functionality.
B
Energy is needed to move sugar from low to high concentration while using a membrane protein.
Explanation:
The reason that energy is needed in this process is that the movement of the molecules is moving up the concentration gradient. This means decreased entropy and increasing Gibbs's free energy.
This is not a spontaneous process and therefore energy input is required. It is called active transport. This is why ATP energy is used to power the process. Atp enables the transmembrane proteins to change conformation and transport the sugar molecules into the cell.
In facilitated diffusion, while the molecules are facilitated by membrane proteins, no energy is input because the molecules are still traveling down the concentration gradient.
