Answer:
In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.
Distance/Time = 120 Km/2 hours =120/2 Km per hour or for short 60 Km per hour
Well in most ecosystems, all the energy in the food chain originally comes from the sun. Plants absorb carbon dioxide from the air and using energy from the sun, the plants turn it into glucose. Then the glucose is transformed into ATP inside the bodies of animals
The process cells use to grow and replace old cells is mitosis.
An eagle is at the top of the food chain. A mountain isn't considered food. Maybe the plants it carries and algae, but the mountain itself is not a food. Mice as we should know is well know to be (depending on the food chain and how many animals you add,) is either close to the bottom or pushing just a taste towards the middle.
