Which compound is a reusable, complex protein that speeds up chemical reactions?
Irina-Kira [14]
Hello there! 

The answer is enzymes. 
Enzymes are biological catalysts, which means they decrease the amount of activation energy needed to start a reaction, therefore speeding up the rate of the reaction. They are part of the protein macromolecule group. Without them, our bodies would not process things efficiently or fast enough for us to live.

Hope I helped. Have a nice day.

Your skeletal stores calcium. How does the calcium get into your body
frosja888 [35]

The calcium get into your body through Vitamin D.

<u>Explanation:</u>

In order to make the bones healthy, calcium and phosphorus is very essential.  Calcium cannot be made by human body. The body only gets the calcium it needs, by means the food you eat, or from supplements. Vitamin D plays a major role in the absorption of calcium in human body. Calcium is a major mineral in a human body that helps in the proper working of body cells and nerves.

The quantity of the minerals like calcium, phosphorous,etc that are present in a segment of bone determines the density of bone. A percentage of 15 to 20 of calcium is absorbed from the diet that human intake. When the levels of vitamin D is low, there will be lower intake to calcium by gut. This causes the bones to become weaker.
