As a fracture is repaired, new bone is added to the injury site. What term is used todescribe the addition of new bone tissue? I
Musya8 [376]

Answer:

The addition of new bone tissue is termed as bone remodeling. In the process of bone remodeling, the tissues of the bone are withdrawn or resorbed from the skeleton and the formation of new bone tissue takes place also known as ossification. The mentioned procedures also monitor the shape of the bones after the incidents like fractures.  

In the process of bone remodeling, two types of cells play an essential part, that is, osteoblast that generates new bone and osteoclasts that dissociates a bone. In the process of bone remodeling, the resorption of the bone takes place by osteoclasts, which is succeeded by bone deposition by osteoblasts. In combination, the cells, which are accountable for bone remodeling are called BMU or basic metacellular unit.

Answer:

Explanation:

The citric acid cycle, also known as the Krebs cycle, is a metabolic pathway by which carbohydrates, lipids and amino acids can be oxidized to carbon dioxide (CO2) and water (H2O). Coenzyme A (CoA) is a key coenzyme in the citric acid cycle. Coenzyme A acts as a carrier of acyl groups: its acetyl-coenzyme A form delivers the acetyl group to the citric acid cycle in order to be oxidized for energy production. During the citric acid cycle, Coenzyme A delivers the acetyl group to oxaloacetate (a four-carbon molecule), in order to form citrate (a six-carbon molecule that contains three carboxyl groups). Subsequently, citrate is oxidized and decarboxylated to produce a succinyl CoA, 2 CO2, and 2 NADH.
