What is the function of proteins and carbohydrates that are embedded in a cell membrane? a. they provide nutrients that the cell needs. b. they control what enters and leaves the cell.

The function of proteins and carbohydrates that are embedded in a cell membrane is:

B. They help control what enters and leaves the cell.

Explanation:

Even though the most common contribution of proteins and carbohydrates is to provide energy to the cell. When they are attached to the membrane they work as catalyst or filter and they decide what type of substances pass through the cell membrane. This happens because their covalent links allow them to balance the membrane and identify the substances required to work properly.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
