The answer is; electromotive force
As the Krebs cycle/ Citric cycle occurs in the mitochondria matrix, hydrogen protons are produced and get accumulated in the inter-membrane space from the matrix of the organelle. It is this electromotive force that is harnessed by the ATP synthase to produce ATP.
Answer:
Organisms interact with each other and their environment in ecosystems. The role of consumers in an ecosystem is to obtain energy by feeding on other organisms and sometimes transfer energy to other consumers. Changes that affect consumers can impact other organisms within the ecosystem.
There is NOT a difference in speed between a car going forwards at 5 m/s and a car moving backwards at 5 m/s.
Speed is just the rate of change of the position of an object. It is calculated by dividing the change in position (distance traveled) by the time it takes to move said distance.
The distance between the two points is always positive because the direction does not matter.
However, if we are looking for the velocity, the direction DOES matter. In this example, the velocity moving forwards is 5 m/s while the velocity moving backwards is -5 m/s.
In other words:
<em>Speed </em>is looking at the <em>magnitude</em>
<em>Velocity </em>is looking at the <em>magnitude </em><em>and </em><em>direction.</em>
Answer:
CO2 and N2 movement in and out of cells is unaffected when membrane protein activity is blocked.
Explanation:
The selective permeability of the biological membranes, like a cell membrane, to small molecules, allows the cell to control and maintain its internal composition.Free diffusion across the lipid bilayer can happen only for small uncharged or nonpolar molecules, such as CO2 and N2. Thus, they can easily cross cell membranes, without the assistance of the transmembrane proteins. Small uncharged polar molecules, such as H2O, also can diffuse through membranes without any help from channel proteins or carrier proteins, which are the two types of transmembrane proteins.
In the case of molecules like glucose, passage across the membrane occurs via the action of specific transmembrane proteins, which act as transporters. These transmembrane proteins allow polar or charged molecules to cross the membrane through a protein pore without interacting with the hydrophobic fatty acid chains of membrane phospholipids.
Your answer is true
