Answer:
True
Explanation:
A general misconception is that insulin is only involved in energy and fat metabolism. When energy needs are high, insulin transports sugar from the blood into the muscle where it can be converted into energy. When energy needs are low, insulin facilitates the conversion of excess sugar into fat where it can be stored for future use.
What is often overlooked is the powerful effect of insulin on stimulating muscle protein growth and repair. An essential action of insulin is to increase the transport into muscle of amino acids, the building blocks of protein, where they can be used for rebuilding and repair. Insulin’s anabolic effects do not end there. Insulin also plays an important role in turning on one of the metabolic switches that control protein synthesis.
This action explains why combinations of carbohydrate and protein are far more effective in stimulating protein synthesis than protein alone. Two switches are responsible for turning on protein synthesis. One is activated by protein, specifically amino acid levels in the blood, and the second by insulin. Consuming carbohydrate (which raises insulin levels) and protein in your recovery drink gives you a dual benefit. In fact, research has shown that a carbohydrate protein drink is 38% more effective than a protein drink in stimulating muscle protein synthesis post exercise.
Another important effect of insulin is inhibition of protein breakdown. At any given time, muscle protein is in a state of flux – it is being synthesized and broken down. When more protein is synthesized than broken down, you have a net gain in lean body mass. After exercise, protein degradation is higher, primarily because during extended endurance activity up to 20% of the working muscle’s energy is derived from protein. That’s why consuming protein in your sports drink offers significant advantages. It reduces the amount of muscle protein used for energy. Higher breakdown rates of protein after exercise increases muscle soreness and slows the overall recovery process. By inhibiting protein breakdown, insulin mediates a faster recovery.
The bottom line – by taking advantage of how and when insulin works and how nutrition can affect insulin activity, endurance athletes can optimize muscle recovery and achieve significant improvements in endurance performance.
The complete question is :
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
Which prediction will most likely describe how friction will affect her findings?
Answer:
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Explanation:
The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.
In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :
F' = F - f
Here, F = the force applied
f = force of friction
And f = μ.N (N = reaction force)
Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.
Answer:
Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.
Explanation:
The species that are mostly to be producers to be plants because they take in the light source aka the sun via photosynthesis. This takes up most of the energy in the ecosystem
The right answer for the question that is being asked and shown above is that: "a decreasing number of viable, fertile hybrids is produced over the course of generations." The phenomenon of fusion is likely to occur when, after a period of geographic isolation, two populations meet is that <span>a decreasing number of viable, fertile hybrids is produced over the course of generations.</span>
