Answer:
The following options are true;
a) Electron transfer in the ETC is coupled to proton transfer form the matrix to the intermembrane space
c)The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions.
d) Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c.
f)Electron carriers are organized into four complexes of proteins and prosthetic groups
Explanation:
ETC involves series of steps in which electrons are passed rapidly from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, producing water. This requirement for oxygen in the final stages of the chain can be seen in the overall equation for cellular respiration, which requires both glucose and oxygen.
A complex is a structure consisting of a central atom, molecule, or protein weakly connected to surrounding atoms, molecules, or proteins. The electron transport chain is an aggregation of four of these complexes (labeled I through IV), together with associated mobile electron carriers. The electron transport chain is present in multiple copies in the inner mitochondrial membrane of eukaryotes and the plasma membrane of prokaryotes.
Answer:
Explanation:
The speed is 0.7 m/s.
The distance covered is 1609 m.
Multiplying both sides by <em>t</em>.
Then dividing both sides by 0.7.
It would take 2298.57 seconds.
Answer:
Heat is similar to and different from internal energy
Explanation:
Similarity:
First thing to remember is that heat and internal energy are both different forms of energy. Secondly, heat is directly proportional to internal energy. When you provide heat to the system, its internal energy will increase. So, heat is the part of internal energy.
Difference:
Internal energy is the summation of kinetic and potential energy of a system, means it depends upon movement of particles as well as the particular position of the system while heat is the transfer of the energy due to difference of degree of hotness and coldness of body or a system.
Oh jk haha LOL bye hahaha
Answer:
Vibrations of the eardrum are in turn translated into oscillations of tiny bones (ossicles) found within the middle ear. The Hammer, Anvil, and Stirrup magnify the oscillations and relay this information to the chamber of the inner ear.
