There are 2 types of transport mechanisms that involve the movement of materials across the cellular membrane:
1. Passive Transport Mechanisms which is the movement of materials that does not require energy. Instead the movement relies on the permeability of the cell. Under this are three kinds of passive transport mechanisms:
a. Simple Diffusion:
- the movement of materials from a region of higher concentration to lower concentration. No external energy is necessary for the movement. The materials supply the energy themselves.
b. Facilitated Diffusion:
- This differs from simple diffusion because the movement is facilitated by proteins that make up the structure of the membrane. The proteins include channel proteins that allow ions and smaller molecules to cross the membrane. The other protein are the carrier proteins, which bind to materials like sugar molecules and move it across the membrane.
c. Osmosis:
- This is the diffusion of water across the membrane. Osmosis moves water from regions where there are more water molecules of water per volume to regions where there are less water molecules per volume.
2. Active transport on the other hand is a movement mechanism that requires energy. It uses the energy to send materials against the direction it is coming from through simple diffusion. This mechanism is used in a way to keep unwanted ions or other materials out of the cell.
Answer:
water motion that is non-linear in nature can cause natural disasters on shorelines.
Explanation:
these natural disasters could be on a small scale or a large scale depending on the strength of that movement of water. Rip currents and storm surges (uncommon) are two different types of hazards that can occur on the coast. In addition, a more dangerous case is a tsunami - which may be triggered by an earthquake - these are ocean waves traveling at a very high speed.
Hope that answers the question. Have a great day!
The
infected papaya trees will produce less carbohydrates or chemical energy for the toucan. If there were fewer carbohydrates within each papaya, the
toucan's muscle cells would not be able to obtain as much chemical energy as
they normally do. This chemical energy will be converted into mechanical energy
or heat flow, which the toucan uses to fly.
Therefore, the lower amount
of mechanical energy and heat flow from the muscle contractions, it would
result into a reduced amount of kinetic energy of motion when the toucan is
flying.
Answer:
d
Explanation:
ATP stands for Adenosine Tri Phosphate, and that third phosphate is bonded to the other two with a very high energy bond, so a lot of energy is released when that bond is broken. When the third phosphate is removed from ATP, you get ADP, which stands for Adenosine Di Phosphate.
