What else can I help you with?
Oxygen molecules enter a cell by diffusion which is?
Diffusion is the movement of molecules or ions from high concentrated medium to low concentrated medium due to the continuous free movement of molecules, simply it's like spraying some perfume , air diffusion makes perfume molecules to move so that you can smell it every where in the room..
What is high energy molecules used by cells?
Adenosine TriPhosphate is a high energy molecule used in the Kreb cycle of the mitochondria, the powerhouse of the cell.
What are the 3 rules for the cell theory?
1. Moving from high concentration to low concentration. 2. Balances out molecules.
How does a cell each equilibrium?
Molecules tend to travel from a concentration from high to low. A cell will reach equilibrium when the concentration gradient has become equal on both sides of a cell (inner and outer membrane). A cell will reach what is called "dynamic equilibrium" when the concentration gradient of a cell is equal, but molecules still move back and forth in the same proportions.
When would active transport be used by a cell?
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
When the salt level is high inside a cell what type of molecules can passively move into the cell?
A high level of salt in a cell would cause water molecules to move passively into the cell.
What occurs when intracellular calcium levels are high?
High intracellular calcium levels can lead to muscle contraction, neurotransmitter release, activation of enzymes, and gene expression. However, sustained high levels of calcium can also be toxic to the cell, leading to cellular damage and eventually cell death.
Does an increase or decrease in potassium extracellular ions hyperpolarize a cell?
An extracellular increase of potassium (increase of intracellular Sodium) causes depolarization. The opposite, I presume, meaning high intracellular potassium (inside cell) and high extracellular sodium (outside cell) would be hyperpolarization
Difference between intracellular fluid and extracellular fluid?
Cytoplasm is the inner part of the cell or its the contents of the cell, which is surrounded by plasma membrane. While extracellular fluid is the fluid located outside of the cells and divided into 1.plasma in the blood vessel. 2.interstitial fluid between the cells.
What direction do molecules move in exocytosis?
In exocytosis, molecules move from inside the cell to outside the cell. This process involves the fusion of vesicles with the cell membrane, releasing the contents of the vesicles into the extracellular space.
What are the name of high energy molecules that run the cell's machinery?
adenosine triphoshate
As the concentration of molecules outside a cell increases more molecules will enter the cell?
Yes, this process is known as osmosis. Water moves from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell) to balance the concentration levels. This causes more molecules to enter the cell as the concentration difference increases.
What term describes this action does it require energy?
1.Small lipid molecules are in high concentration outside a cell. They slowly cross the membrance into the cell. 2. Ions are in low concentration outside a cell they move rapidly into the cell via protein molecules.
How would you define diffusion?
Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.
Glucose is a molecule that can move across the cell membrane if the concentration of glucose is high or inside the cell than outside the cell then what will happen by the process of diffusion?
glucose molecules will diffuse out of the cell. apex
Oxygen molecules enter a cell by diffusion which is?
Diffusion is the movement of molecules or ions from high concentrated medium to low concentrated medium due to the continuous free movement of molecules, simply it's like spraying some perfume , air diffusion makes perfume molecules to move so that you can smell it every where in the room..
If water moves into a cell and the cell swells what terms describes the environment inside the cell?
The term you're looking for is hypotonic, which basically refers to having reduced pressure or tone. In Biology, hypotonic refers to having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
