A cell’s digestive enzymes are enclosed in a membrane-bound organelle. How can these molecules function in the cell?

Answers

Answer 1

Answer:

A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

Explanation:

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily

How does Islands formed?

Oceanic islands are those islands which rise to the surface of land from the floors of the ocean basins. Continental islands are simply the unsubmerged parts of continental shelf which are entirely surrounded by water from all the sides. Many of the larger islands of the world are of the continental type only.

As volcanoes erupt, they build up different layers of lava which may eventually break the water surface. When the tops of these volcanoes appear above the water level, an island is formed. While the volcano is still beneath the ocean surface, it is known as a seamount. Oceanic islands can form from the different types of volcanoes.

Put the steps of DNA Replication in the correct order ​

Answers

Answer: Initiation Elongation and termination

Explanation:

There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.

The correct order for DNA replication is B, A, C and D.

During DNA replication, first the DNA double helix break down the middle part between base pairs. The enzyme DNA polymerase moves along the exposed strands and adds complementary nucleotides to each nucleotide in each existing strand.

After that a complementary strand is produced for each of the two strands of the original double helix. Thus two new identical DNA molecules have been produced and the replication process is finally completed.
