How many molecules of ATP are gained by substrate-level phosphorylation from the complete breakdown of a single molecule of glucose in the presence of oxygen?

In substrate level phosphorylation, the ADP is phosphorylated directly by the transfer of phosphate group from substrate. If we consider glucose, then we get four substrate level phosphorylated ATPs, net gain of two in glycolysis and other two are formed when the two pyruvate molecules formed after glycolysis enter the TCA cycle.

Will electricity make a visible arc in a vacuum?
Not in a complete vacuum, you need some molecules present to be stimulated
All molecular motion ceases at 0 Kelvin why?
All molecular motion stops at absolute zero because absolute zero is the coldest possible temperature. And it is only able to achieve this temperature if the molecules/atom do not possess any thermal energy. And thermal energy is what causes vibrating motion of the molecules/atom. Thus at this temperature no molecules/atoms will vibrate due to the complete lack of energy.
How can you write with a pencil?
A sharp point on a pencil will be eroded by a rough surface (paper) and leave a coating of graphite. This does not immediately penetrate the paper and can be erased. After some time, the paper will absorb some graphite molecules into its structure, and erasures will not be complete.
How is the temperature of a gas related to the kinetic energy of its particles?
Ok, i am currently on this subject right now and im in 7th grade, so, here goes... the temperature affects the kinetic energy of water molecules by slowing the molecules as the temperature gets cooler and when u heat up the water, the molecules spread out and bounce around. the colder, the more stuck together, more still and close they r. when they r warmer they r the complete opposite. hope that's good enough (:
How are explosions different from other chemical reactions?
Yes, combustion is a chemical reaction, because it is a reaction between a molecule and oxygen (O2) to produce a new molecule plus CO2 (if it's a complete combustion) or CO (if it is an incomplete combustion). Combustion is also an exothermic reaction, which means that heat is released.
The complete breakdown of glucose in the presence of oxygen yields how many molecules of ATP?
36 molecules by oxydative phosphorylation.

The complete breakdown of a glucose molecule during oxidative respiration requires six oxygen molecules is that true or false?
true
Does cellular respiration cause most organic molecules?
I wouldn't say that. The main purpose of respiration, that in biochemistry is known as "oxidative phosphorylation" is to produce ATP molecules. A complete chain of an oxidative phosphorylation pathway goes from a molecule of glucose that is degraded into smaller molecules, passing through tricarboxylic acid cycle and a redox loop mechanism (in mitochondria) to produce molecules of water and CO2.
Where is respiration started?
Respiration has 3 main steps:1. Glycolysis - initial breakdown of glucose2. Krebs Cycle/Citric Acid Cycle - complete breakdown of glucose into CO23. Electron Transport Chain and Oxidative Phosphorylation - use of energy released duringglucose breakdown to produce ATPGLYCOLYSIS:*the breakdown of glucose to produce 2 molecules of pyruvate*requires breaking bonds*exergonic process, energy is released*each molecule of glucose (C6H12O6) is split into 2 three carbon sugars*during the breakdown of glucose, electrons are released*these electrons are stored in 2 molecules of NADH (reduced coenzyme)*the electrons are released later in the electron transport chain (Step 3)*glycolysis occurs in the cytoplasm (does not require mitochondria)*glycolysis requires an investment of energy in order to produce energy*2 ATP used during energy investment phase*4 ATP produced during energy payoff phase*Net: 2 ATP produced during glycolysis per glucose moleculeEquation: C6H12O6 + 2ATP --> 2 pyruvate + 4ATP + 2NADH + 2H2O
