The plasma membrane is composed of a phospholipid bilayer with embedded proteins. what is one of the functions of the embedded proteins? a. protecting the cell from physical harm b. allowing specific substances to flow into the cell c. defining the cell's structure and shape d. preventing the phospholipid tails from binding together

B - the proteins can act as channels. They let substances that are dissolvable in ionic substances through. They are needed as the phospholipid bilateral dose not allow this.

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
