Answer:
6CO2 + 6H2O -> C6H12O6 + 6O2
The primary energy system to fuel cycling for 15 minutes is THE AEROBIC GLYCOLYSIS SYSTEM.
There are different energy systems for fueling different types of physical exercise, the type of system that is used depend on the duration of the physical exercise. The energy system that exist are anaerobic glycolysis, aerobic glycolysis, phosphagem system and fatty acid oxidation. The aerobic glycolysis energy system relies on the complete breakdown of glucose. The pyruvate which is the end product of glucose oxidation is further broken down to acetyl coA, which then enters into the citric acid cycle. The aerobic glycolysis energy system is used for physical exercises that last between three to twenty minutes.
Answer:
Endocardium
Explanation:
The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.
The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.
Answer:
cells, growth, reproduction, adaptation, homeostasis, use of energy and response to the environment
<span>Colostrum
is replaced by transitional milk in about 2 to 4 days after birth. This milk
contains high levels of lactose, fat, vitamins and more calories than the
colostrum. Mature milk replaces the transitional milk and begins to appear near
the end of the second week after childbirth. Mature milk contains more water than
transitional milk.</span>
