What process does a cell with a low concentration of oxygen will likely gain oxygen molecules from an area with a higher oxygen concentration have to go through?
Diffusion.
If you held your breath what would happen to the concentration of oxygen in your lungs?
If you held your breath, the concentration of oxygen in your lungs would decrease. The concentration of carbon dioxide would increase in your lungs.
How can pollution affect the level of oxygen in water?
The concentration of oxygen in waters decreases.
How many oxygen atoms are there in the formula for aluminum nitrate?
The formula for aluminum nitrate is Al(NO3)3, so there are 9 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
Where in the mitochondrion do protons accumulate?
In the outer lumen and they are stripped from the derivatives of glucose along with electrons used in electron transport. Protons are moved across the inner membrane of the mitochondria by the action of electrons moving down the electron chain where the final acceptor is oxygen. The protons build up a concentration and move back down their concentration gradient through ATP synthase and produce said ATP.
What role did diffusion play in the changes you observed?
Before diffusion there is a higher concentration of oxygen molecules outside the cell than inside the cell. After diffusion the concentration of oxygen molecules is the same outside and inside the cell.
How does oxygen and carbon dioxide enter and leave the cell?
By passive diffusion down its concentration gradient, which requires no energy expenditure from the cell. Basically, if you have more oxygen outside a cell than inside a cell, it travels through channels or holes in the cell membrane until the concentration of oxygen is equal inside and outside the cell.
What is diffusion of oxygen all about?
Diffusion is the main method by which molecules move across the cell membrane. during diffusion, molecules move from an area of higher concentration, to an area of lower concentration. What is Osmosis? Osmosis is the transport of water from an area of high concentration, to an area of low concentration water moves inside and inside of the cell membrane by osmosis. osmosis is the diffusion of water!
Why is the concentration of oxygen on either side of the double membrane of a chloroplast different?
no i cant answer this
When molecules such as oxygen are moved into Cells along their concentration gradient directly through the Cell membrane - this is called?
Trans-membrane diffusion.
What is the role of diffusion within a cell?
Diffusion is an intermingling of molecules, ions, etc., resulting from random thermal agitation, as in the dispersion of a vapor in air. When there is a higher concentration of oxygen molecules outside the cell than inside the cell, diffusion takes place by causing the concentration of oxygen molecules to be the same outside and inside the cell.
How does oxygen get in and out of plasma membrane?
Oxygen, O2, is a small enough molecule that it diffuses diwn it's concentration gradient into the cell and rather easily foes through the plasma membrane. Many small molecules can do this.
How do CO2 and O2 move in and out of a plant leaf?
If you take a cross-section of a leaf and magnify it several times, you will see tiny pores on the underside. These holes are called stomata, and gaseous transfer takes place here, with carbon dioxide and oxygen entering and circulating inside the leaf. Waste gases from photosynthesis and respiration leave through the stomata as well. The oxygen diffuses out of the leaf because the concentration of oxygen is greater outside rather than inside the leaf (diffusion is the random movement of particles from an area of high concentration to an area of low concentration), down the concentration gradient. Likewise, the carbon dioxide diffuses into the cell because the concentration of carbon dioxide is greater outside the leaf than inside.
What is an accurate summary of chemiosmosis?
Oxygen diffuse down their concentration gradient out of the stoma into the grana through ion channels in the membrane.
Oxygen and carbon dioxide cross the plasma membrane by what process?
They are carried by the hemoglobin in your blood. The red blood cells carry the carbon monoxide through the pulmonary artery from the heart to the lungs and from the heart the oxygen goes into the aorta to the rest of your body. == ==
What explains the fact that the net movement of oxygen is always into the cell?
The net movement of oxygen into the cell is primarily driven by concentration gradients. Oxygen concentration is typically higher in the extracellular environment than inside the cell, creating a concentration gradient that favors the movement of oxygen from higher to lower concentration. This allows oxygen to diffuse into the cell until equilibrium is reached, ensuring the cell has sufficient oxygen for its metabolic needs.
What is the process known as when carbon dioxide enters leaves?
Photosynthesis. The reaction where CO2 enters the leaves through diffusion and is released as O2. Diffusion - The movement of particles from an area of high concentration to an area of low concentration - From the air (area of high concentration) to inside the leaf (area of low concentration). In photosynthesis, the chlorophyll (green substances inside the leaf cells) convert the CO2 along with water taken up the roots to create oxygen and glucose. The glucose is used by the plant to produce fruits and to take up water by the roots. The oxygen diffuses out of the leaves as there is a higher concentration of oxygen inside leaf then there is outside the leaf. The word equation for photosynthesis is: Carbon Dioxide + Water --> Oxygen + Glucose The symbol equation for photosynthesis is: 6CO2 + 6H2O --> 6O2 + C6H12O6
