Do substances in diffussion move with the concentration gradient?
Yes, substances in diffusion move from an area of high concentration to an area of low concentration, following the concentration gradient. This process continues until equilibrium is reached, with equal concentration on both sides.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
Can passive membrane transport processes include movement of water from an area of low concentration to an area of high concentration?
No, passive membrane transport processes do not involve movement of substances from areas of low concentration to areas of high concentration. Instead, passive processes such as osmosis and diffusion move substances down their concentration gradient, from areas of high concentration to areas of low concentration without requiring energy input.
Based on diffusion what will happen to the substances inside and outside of the cell?
Substances will move from an area of high concentration to an area of low concentration in order to achieve equilibrium. Inside the cell, substances will diffuse out if the concentration outside is higher, and substances will diffuse in if the concentration outside is lower, until equilibrium is reached.
Does diffusion go from high concentration to low concentration?
Yes, they move from high, to low.
Why are acidic substances lower in pH value than basic substances?
Acidic substances have higher concentrations of hydrogen ions (H+) which results in a lower pH value compared to basic (alkaline) substances. A lower pH value indicates a higher concentration of H+ ions, while a higher pH value indicates a higher concentration of hydroxide ions (OH-) found in basic substances.
When substances pass through diffusion they move from areas of their what to areas of their what?
it moves from high to low concentration
Do bases have a high or low concentration of OH- ions?
Bases have a high concentration of OH- ions. When bases dissolve in water, they release hydroxide ions (OH-) which can accept protons to form water. This interaction is responsible for the basic properties of these substances.
Does passive transport move substances against the concentration gradient?
No, passive transport does not move substances against the concentration gradient. It moves substances from an area of high concentration to an area of low concentration without requiring energy input.
Do substances in diffussion move with the concentration gradient?
Yes, substances in diffusion move from an area of high concentration to an area of low concentration, following the concentration gradient. This process continues until equilibrium is reached, with equal concentration on both sides.
Do Substances naturally diffuse up a concentration?
no down a concentration gradient high to low if its low to high it requires energy
Is active transport low to high?
Yes, active transport moves substances from an area of low concentration to an area of high concentration.
How does active transport enable the movement of substances from a low concentration to a high concentration within a cell?
Active transport is a process in which cells use energy to move substances against their concentration gradient, from an area of low concentration to an area of high concentration. This allows the cell to maintain specific concentrations of substances inside and outside the cell, which is important for various cellular functions.
What drives the diffusion of substances across a membrane?
The diffusion of substances across a membrane is driven by the concentration gradient, which is the difference in concentration of a substance on either side of the membrane. Substances naturally move from areas of high concentration to areas of low concentration in order to reach equilibrium.
How are the 3 passive transports different?
Simple diffusion - High concentration to low concentration, no energy required osmosis - Movement of water across a membrane, no energy required facilitated diffusion - Movement of substances, protein's are used to help move the substances across the membrane. There are very basic summaries of each.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is acid or alkaline mean?
Acidic substances have a pH value below 7, indicating a higher concentration of hydrogen ions. Alkaline (or basic) substances have a pH value above 7, indicating a lower concentration of hydrogen ions and a higher concentration of hydroxide ions. This pH scale ranges from 0 to 14, with 7 being neutral.
