- What supply the activation energy needed for this process?
- 2 ATP molecules
- What are also given off in the formation of pyruvic acid?
- four hydrogen atoms
- Enough energy is released in splitting the glucose atom to form what?
- four ATP molecules thus the net gain of 2 ATP molecules
- What can hydrogen acceptors do?
- bind hydrogen atoms released in chemical reactions and release them when needed
- What is the reason most organisms can't live without oxygen?
- the next step involves oxygen
- What is the main result of the reactions in glycolysis?
- glucose molecule is broken down to a 3-C molecule of pyruvic acid
- Where does the first stage of glycolysis occur?
- outside the mitochondrion or the cytoplasm
- What process is called aerobic respiration?
- when pyruvic acid follows this pathway
- What is required for the process after glycolysis?
- oxygen
- Glycolysis does not require what?
- oxygen
- As many as how many enzymes are used in the series of reactions in glycolysis?
- 12
- Four hydrogen atoms join to a what?
- coenyzme, nicotinamide adenine dinucleotide or NAD
- What happens to the organisms after glycolysis depends on what?
- the type of organism and availability of oxygen
- What is NAD?
- an electron acceptor
- The four hydrogen atoms are joined to two what molecules to give what?
- NAD, 2NADH+H+
- In most organisms, what is the next step after glycolysis?
- the breakdown of pyruvic acid to carbon dioxide and water with the release of energy
- The energy released in the first stage of respiration is about 1% of what?
- the total energy available in the glucose molecule. the rest of its energy remains in the bonds of the pyruvic acid molecules
- The NAD become what?
- NADH+H+
