What is the most important distinction between the membrane transporters known as channel proteins and those known as carrier pr
-Dominant- [34]

Answer:

Channel proteins form hydrophilic channels to passively transport substances down the concentration gradient.

Carrier proteins bind to substances to transport them actively against the concentration gradient. They do not form channels.

Explanation:

Channel proteins are the membrane proteins that serve in transport of small polar molecules and/or ions by making a hydrophilic pore across the membrane. These molecules diffusion through the pore and exhibit facilitated diffusion.  

Carrier proteins are the membrane proteins that transport the substances across the membrane by binding to them. They do not form the hydrophilic channels. Carrier proteins serve in the active transport of molecules against the concentration gradient.

Which of the following modifies and smoothes the respiratory pattern?
stealth61 [152]

The correct answer is: A) pontine respiratory centers

The respiratory centre in the pons is responsible for generating and maintaining the rhythm of respiration. Besides this elementary function, it also has the ability to adjust respiration rhythm in c response to physiological changes. Respiratory centre consists of three major respiratory groups of neurons:

•  The dorsal respiratory group (DRG)- initiates inspiration (inhalation)

• the ventral respiratory group (VRG)-responsible for exhalation

• Pontine respiratory group- includes the pneumotaxic (controls both the rate and the pattern of breathing) and apneustic centers (promotes inhalation by sending signals to dorsal group).

Assignment: 01.03 Transformation of Energy
trasher [3.6K]

The energy transformations that occur in the given devices are as follows:

  • Windmill - mechanical energy to electrical energy
  • Flashlight - electrical energy to light energy
  • Microwave - electrical energy to heat energy
  • Firecracker - chemical energy to heat, light, and sound energy
  • Bicycle - Chemical energy to mechanical energy
  • Battery - chemical energy to electrical energy

<h3>What is energy transformation?</h3>

Energy transformation refers to the processes by which one form of energy is transformed into another form.

The law of conservation of energy guides the various energy transformations that occur in the universe.

The law of conservation of energy states that energy is neither created nor destroyed but can be transformed from one form to another.

The energy transformations that occur in the given device are as follows:

  • Windmill - mechanical energy to electrical energy
  • Flashlight - electrical energy to light energy
  • Microwave - electrical energy to heat energy
  • Firecracker - chemical energy to heat, light, and sound energy
  • Bicycle - Chemical energy to mechanical energy
  • Battery - chemical energy to electrical energy

In conclusion, energy transformations occur according to the law of conservation of energy.
