What do you think might happen if someone had a mutation that didn't allow his or her body to make carbonic anhydrase?

The absence of this enzyme leads to different types of diseases in the body.

If someone had a mutation that didn't allow the body of an individual to make carbonic anhydrase then the carbondioxide that is produced in the respiration reaction will not converted into carbonic acid and bicarbonates. This conversion is important in order to remove the carbondioxide which is a waste material from the body.

The person experiences various problems due to lack of this enzyme such as excess ammonia in the blood, acid-base balance in the blood and low glucose in the blood so we can say that absence of this enzyme creates big problems in the body.

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.

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.
