What enzyme is found in the inner mitochondrial membrane?
What enzyme is found in the inner mitochondrial membrane? ATP synthase What is the difference between Chemiosmosis and oxidative phosphorylation? oxidative phosphorylation: A metabolic pathway that uses energy released by the oxidation of nutrients to produce adenosine triphosphate (ATP). chemiosmosis: The movement of ions across a selectively permeable membrane, down their electrochemical gradient.

Does each bird have a unique song?
Does each bird have a unique song? Each bird species typically has its own unique song. That allows an individual bird to hear a song and recognize whether the singer is from its own species.

Is the force between the wires attractive or repulsive?
Is the force between the wires attractive or repulsive? Parallel wires carrying currents will exert forces on each other. One wire sets up a magnetic field that influences the other wire, and vice versa. When the current goes the same way in the two wires, the force is attractive. When the currents go opposite ways, […]
Can I self study physics?
Can I self study physics? You can take a look there. I studied physics and think the scripts and materials listed there, are really comprehensive to study the most important topics on physics. You should solve as many problems as you can find to learn a theory. Don’t just read texts or books. Which book […]

What is the total charge of oxygen?
What is the total charge of oxygen? -2 Does atomic mass change in beta decay? The atomic mass number does not change because a beta particle has a much smaller mass than the atom. The atomic number goes up because a neutron has turned into an extra proton. Beta decay is fundamentally different from alpha […]
