What else can I help you with?
Which structure is most necessary for mitochondria to produce new molecules?
Hydrogen pump.
What substance cannot be moved into a cell by osmosis or diffusion?
Large molecules such as proteins cannot be moved into a cell by osmosis or diffusion due to their size and charge. These molecules require specialized transport mechanisms such as active transport to enter the cell.
What is a protein pump?
it is a protein in a quatenary structure or three d sturucture with in the cell wall and transports macro molecules, hydrophobic molecules or molecules that are going agains the concentration(respectively are to big to go through, repel the cell wall, or are going against the traffic of osmosis) by using those molecules as a substrate( something that fits into a protein) and moves to the other side of the wall
What is moved into cytoplasm?
Messenger RNA (mRNA) molecules are moved into the cytoplasm in eukaryotic cells after they are transcribed in the nucleus. This mRNA carries the genetic code from the DNA and is used by ribosomes to synthesize proteins.
How does the pump protein function in the process of cellular transport?
The pump protein helps move molecules across the cell membrane by using energy to pump them against their concentration gradient. This process is essential for maintaining the balance of substances inside and outside the cell.
How many molecules of sodium and potassium are moved and in which direction are they moved in?
In the sodium-potassium pump, three sodium ions are moved out of the cell and two potassium ions are moved into the cell. This process helps maintain the cell's resting membrane potential and is crucial for nerve and muscle function.
What is moved by active transport?
Molecules are moved by active transport.
How molecules moved?
Molecules usually move from high concentration to lower concentrations.
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
Molecules pumped in or out from low to high concentration?
This process is called active transport. Molecules are moved against their concentration gradient, from an area of low concentration to an area of high concentration, with the help of energy input, typically from ATP. Examples include the sodium-potassium pump and the proton pump.
What pumps small molecules in and out of cells?
PUMPS (proteins) pump molecules in and out of the cell by using energy
What type of solute molecules may be moved by diffusion?
Many polar molecules and ions with the assistance of transport proteins.
What makes a mechanical fuel pump to pump?
A diaphragm inside that is moved back and forth normally by the crankshaft or cam.
What method carries molecules and pump molecules or form channels through which specific molecules pass across the plasma membrane?
Active transport is a method that carries molecules across the plasma membrane against the concentration gradient. This process uses energy, usually in the form of ATP, to pump molecules or form channels through which specific molecules can pass. Examples include the sodium-potassium pump and ion channels.
What is the maximum distance molecules of a medium are moved from a rest position?
AMPLITUDE
Which structure is most necessary for mitochondria to produce new molecules?
Hydrogen pump.
What occurs during the single cycle of the sodium potassium exchange pump?
Three sodium ions are moved out of the cell for every ATP hydrolyzed by the pump. At the same time, two potassium ions are moved into the cell.
