What is respiration of Paramecium?
A paramecium exchanges gases directly with its environment through the cell membrane.
Where do ions diffuse across membrane to specific ion channels?
down their electrochemical gradients.
Where does respiration happen in eukaryotes and in prokaryotes?
In eukaryotes respiration happens in the mitochondria and in prokaryotes the mechanisms of respiration are in the cell membrane as protons must be taken in through the membrane.
Where do we find ions gradients in cell membranes?
Gradiend occurs between two places. Mainly either sides of membrane
How does the arrangement of the cristae in the inner membrane of the mitochondria affect the rate of aerobic respiration?
The rate of aerobic respiration in the mitochondria is dependent on the surface area of the cristae because energy potential is built up through the pumping of hydrogen ions across the membrane. With more membrane surface area, there is more energy production and storage capacity so the rate of aerobic respiration may increase.
What is Respiration paramecium?
A paramecium exchanges gases directly with its environment through the cell membrane.
What is respiration of Paramecium?
A paramecium exchanges gases directly with its environment through the cell membrane.
Why must transport proteins be located in the mitochondrial membrane to complete the third stage of aerobic respiration?
They must interact with the electrons and hydrogen.
What is the pumping of materials across a membrane against their concentration gradients?
Active Transport
Where do ions diffuse across membrane to specific ion channels?
down their electrochemical gradients.
Where does respiration happen in eukaryotes and in prokaryotes?
In eukaryotes respiration happens in the mitochondria and in prokaryotes the mechanisms of respiration are in the cell membrane as protons must be taken in through the membrane.
What drives diffusion?
Diffusion is the movement of ions and other micro molecules across a barrier or membrane. Diffusion is caused by gradients on either side of the membrane.
Which affects the rate of diffusion through a semipermeable membrane?
steeper concentration gradients, higher temperatures and size of the molecule diffusing
Facilitated diffusion carrier proteins and cell membrane pumps both?
They both transport substances up their concentration gradients.
Where do we find ions gradients in cell membranes?
Gradiend occurs between two places. Mainly either sides of membrane
A single mitochondrion consists of?
An outer membrane and an inner membrane, the inner membrane being used during cellular respiration
What membrane attaches directly to the lungs?
The pleural membrane.
