But since they were frozen in such a dense mass, the shrimp got waterlogged before they had a chance to defrost. If you encounter a shrimp block in the future, keep it in its bag and sink the whole thing in a bowl of cool water (like you would defrost chicken or a steak). Then, once itâs softened you can run under cool water to finish the job if necessary.
Definition - What does Acrosome Reaction mean? The acrosomal reaction is the process of two sex gametes, known as the egg cell and the sperm cell, fusing together, causing fertilization. Acrosomal reactions are an essential step of conception, and any abnormality can prevent fertilization and cause infertility.
The sperm first burrow through the cells of the corona radiata. Then, upon contact with the zona pellucida, the sperm bind to receptors in the zona pellucida. This initiates a process called the acrosomal reaction in which the enzyme-filled âcapâ of the sperm, called the acrosome, releases its stored digestive enzymes. These enzymes clear a path through the zona pellucida that allows sperm to reach the oocyte.
