When there is a low concentration of CO2 inside the lead do the stomata open or shut?
Hey, I figured it out when there is a low concentration of CO2 in the leaf the Stomata opens.
What direction are substances said to diffuse?
if something diffuses e.g. particles through the air or CO2 out of body cells means the particles go from a high concentration to a low concentration
What is the Diffusion of gases between alveoli and blood?
The Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the blood. So blood that is pumping through the capillaries in the lungs has a low concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2. Therefore the 2 gases exchange across the alveoli membrane by diffusion trying to establish a concentration gradient.
How co2 particles move from the blood to the alveoli?
They diffuse through the membrane.Diffusion is the movement of gaseous particles from a high concentration of particles, to a low concentration.Using your example of CO2, there is a high ammount of CO2 in de-oxygenated blood, so it travels to the alveoli through the membranes, where there is a lower concentration of CO2.Remember, near every alveoli there is a capillary, which makes this possible.
Would the stomata open or close if the CO2 concentration decrease?
Opening and closing of stomata is regulated by concentration of water in guard cells. When transpiration is required, water reaches the guard cells and they swell up. This opens the stomata's pore. When they are not required to be opened, water is not present in guard cells and they shrink causing stomata's pore to close.
What are low concentrated solutions?
low concentration means more of a substance can be dissolved in the solvent
When the CO2 concentration in the cells of a c3 plant is low compared with the o2 concentration an enzyme combines rubp with o2 rather than with CO2 what affect would this have on photosynthesis?
Since photosynthesis requires the carbon from CO2 and its not getting it, the entire process could come to a halt. This would usually occur in hot and dry conditions, where in higher temperatures, the enzyme has a higher affinity for binding to O2 than CO2.
When molecules move down the concentration gradient it means they are moving from high to low or low to high?
An area of higher concentration to an area of lower concentration.
Does endocytosis go from a high to low or low to high concentration?
Exocytosis goes from high to low concentration.
How do you treat low carbon dioxide in blood?
High CO2 in the blood is corrected by increasing the rate of respiration. By breathing more you take in more oxygen and let out more CO2. High CO2 in the atmosphere is corrected by photosynthesis which uses light and CO2 as energy and releases oxygen as a product.
What are the three rules that apply to diffusion?
Form high to low concentration molecules balenced water goes where their is more concentration
Why is blood so sensitive to pH changes?
well...too much CO2 in the body means there's a high H+ concentration.... which means there's low pH.
