I think the egg because it’s the start of their life cycle, or something. I don’t think the chicken came first bc the egg would be the baby and the chicken the adult.
The pectoralis major muscle can be divided into groups of
fibers superior, or claviclular, and inferior, or sternocostal.
<span>Pectoralis is a major muscle fundamentally responsible for
shoulder joint movements. It is divided
into four actions and two groups of fibers, anatomically the superior side and
interior side. These movements are often
used in everyday lives like throwing and flapping the arms.</span>
The negative feedback principle in human physiology is involved in this case. The inciting factor here is the increase in blood glucose that will be recognized by the pancreatic islet cells (the endocrine part of the pancreas) and will signal insulin release. Insulin upregulates glucose transporter proteins in cells, especially muscle cells, which will then stimulate glucose uptake from blood. Insulin also stimulates glycogen formation in the liver. These events will subsequently lower blood glucose and low blood glucose will now inhibit the insulin secretion by the pancreas. In the event of hypoglycemia or dangerously low blood glucose, the first adaptive mechanism of the body is to produce glucagon from the pancreatic islet cells. Glucagon will stimulate glycogen breakdown in the liver and therefore raise blood glucose levels to normal.<span> </span>
Answer;
B is the product of enzyme 1 and the substrate for enzyme 2.
Explanation;
-Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy.
-The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.
