Are ATP synthases channels for the passage of hydrogen ions?
Yes. Cellular respiration involves three steps: glycolysis, the Krebs Cycle (also called the Citric Acid Cycle) and the Electron Transport Chain. Glycolysis breaks up glucose into two molecules of pyruvic acid, the Krebs Cycle strips away carbon from these pyruvic acids in order to free up electrons, and the Electron Transport Chain takes these electrons and uses oxygen to pull them down a series of proteins, moving hydrogen across the internal membrane of the mitochondria in the process. ATP synthase takes these hydrogen protons as they move back down their concentration gradient and uses them to make ATP.
What process occurs after glycolysis?
aerobic oxidatio of pyruvic acid after pyruvic acid is form it get transfer to mitochondria. as soon as pyruvic acid enter to mitochondria it get oxidise to c02 in the reaction called oxidative decarboxylation. here 1st it get decarboxylate and then it get oxidised by the help of enzyme called pyruvate dehydrogenase. nd this enzym is made up of decarboxylase,lipoic acid amid tpp [thiamine pyrophosphate] nd in the presence of some cofactor such as vit b1 nd mg ions. reaction given below pyruvate + NAD+ + co-A = acetyl co-A + NADH + H+ + c02
Significance of Krebs cycle?
Krebs cycle is process and a syage of respiration carried out in the cells mitochondrion ,Krebs cycle produces alot of reduced NAD (nicotinamide adenine dinucleotide) compared to other stages of respiration...these reduced NAD carries a great deal of energy,meaning one reduced NAD molecule can form 3 molecules of ATP (energy yielding molecule) this formation of 3 atps occurs also in the mitochondrion in a process called chemisomosis. now since Krebs cycle forms alot of reduced NAD, the more reduced NAD formed the more ATP prodcuced through chemisomosis,so more energy u get to carry on ure daily metabolism (meaning more energy to walk or work ;P)
What is the relationship between the Krebs cycle and the electron transport chain?
Electron transport cannot proceed if protons cannot be pumped across the inner membrane. Protons cannot be pumped unless the available energy to move them out of the matrix exceeds the required amount plus what energy is lost to heat.
Where does the cellular respiration occur?
In Every Body Cell AND / OR In Every Living Cell

High energy electrons that move down the electron transport chain ultimately provide the energy needed to?
of course it is break glucose into pyruvic acid.

Explain what happens in the electron transport chain?
as electrons from the Krebs cycle move down the electron transport chain energy level is reduced.
How is ATP made in the cellular respiration process?
It is a very long and detailed process. Generally one glucose molecule gives 38 or 36 ATPs during aerobic respiration. While during anaerobic respiration only 2 ATPs are formed from single glucose molecule. The ATP formation in respiration starts with glycolysis, in which one glucose molecule breaks into 2 pyruvic acid molecule. Then the pyruvic acid is converted to acetyl coA. This acetyl coA enters the Krebs cycle. Finally the NADH2 and FADH2 obtained during Krebs cycle go to electron transfer chain in which maximum ATPs are generated. This is applicable to aerobic respiration. In anaerobic respiration the pyruvic acid is reduced to alcohol and carbondioxide.

Does organisms need energy?
Organisms use energy to divide, grow, remove wastes and to make protein. The organisms are able to do this by the process of the Krebs Cycle.
What is the cyle in which matter and energy move through various steps on earth?
Biogeochemical cycle is the cycle in which matter and energy move through various steps on earth.
What is a process with no beginning or end and ivolves steps that move in a predictable pattern?
A cycle is a process with no beginning or end. Cycles involve steps that move in a predictable pattern. At the end of the cycle, you find that you are back at the beginning.The water cycle is one example of a cycle in nature.
What makes the water cycle move?
The sun's energy
