Answer:

v

Explanation:

1. These vascular plants can both live in moist and dry places.

2. Conifers produce massive amounts of pollen grains and they're carried by the wind. This definitely allows the vascular plants to spread out more across their environment

True or false, the more lean muscle mass, the more responsive your body will be to insulin.
Naily [24]

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 structure of the cell membrane allows it to be selectively permeable. What is the name for the larger, brown structure in th
Anika [276]

Explanation:

B) protein channel

Lipids are composed of fatty acids which form the hydrobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backone) with up to 36 carbons.

Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via <em>diffusion,</em> small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

  • Carrier proteins (also called carriers, permeases, or transporters) bind the specific solute to be transported and undergo a series of conformational changes to transfer the bound solute across the membrane. Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules  which are typically prevented from moving across the membrane.
  • Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane,  from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion
