The answer to this question would be: 14%
Protein will give a calorie about 4kcal/gram. Then, the total calorie of protein from Susan meal would be: 70 grams * 4kcal/g= 280 <span>kilo calorie</span>.
To find the percentage you will need to divide the total calorie diet with the protein calorie. The calculation would be:
protein percentage= protein calorie/ total calorie
protein percentage= 280kcal / 2,000kcal = 14%
Answer: B) proteins in the membrane act like gates to control entrance and exit of molecules.
Explanation: Plasma membrane is composed of phospholipids bilayer in which the hydrophobic regions of the phospholipids face each other to form the core of the bilayer. Proteins are embedded in the bilayer through an interaction between the amino acid side chains and the nonpolar acyl chains of the phospholipids. The embedded membrane proteins form channels for passage of ions and other molecules. Each membrane protein is selected for one or more ions or molecules that passes through it. The membrane is said to be semipermeable because it allows the passage of some molecules and excludes the passage of others.
