Which term describes the degree to which an element attracts electrons?
Which terms describe two atoms when they form a bond in which electrons are completely transferred from one atom to the other?
Anion and cation.
Which of the following statements is true of the bonds in a water molecule?
Oxygen holds electrons more tightly than hydrogen does, and the net charge is zero
Which of the following statements is not true of most cellular redox reactions?
A hydrogen atom is transferred to the atom that loses an electron
What kind of bond is formed when lithium and fluorine combine to form lithium fluoride?
Gaseous hydrogen burns in the presence of oxygen to form water:
Which of the following best describes the main purpose of the combined processes of glycolysis and cellular respiration?
transforming the energy in glucose and related molecules in a chemical form that cells can use for work
In the combined processes of glycolysis and cellular respiration, what is consumed and what is produced?
Glucose is consumed, and carbon dioxide is produced.
Why does the oxidation of organic compounds by molecular oxygen to produce CO2 and water release free energy?
Electrons are being moved from atoms that have a lower affinity for electrons (such as C) to atoms with a higher affinity for electrons (such as O
Which of the following statements describes the results of this reaction?
C6H12O6 is oxidized and O2 is reduced.
When a glucose molecule loses a hydrogen atom as the result of an oxidation-reduction reaction, the molecule becomes
When a molecule of NAD+ (nicotinamide adenine dinucleotide) gains a hydrogen atom (not a proton), the molecule becomes
Where does glycolysis take place in eukaryotic cells?
The ATP made during glycolysis is generated by
The oxygen consumed during cellular respiration is involved directly in which process or event?
accepting electrons at the end of the electron transport chain
Why are carbohydrates and fats considered high energy foods?
They have a lot of electrons associated with hydrogen.
Acetyl CoA Formation
Cellular locations of the four stages of cellular respiration
Citric Acid Cycle
Redox (oxidation-reduction) reactions in glycolysis
Energy from glycolysis
pyruvate, ATP, and NADH
The ATP that is generated in glycolysis is produced by substrate-level phosphorylation, a very different mechanism than the one used to produce ATP during oxidative phosphorylation. Phosphorylation reactions involve the addition of a phosphate group to another molecule.
How many NADH are produced by glycolysis?
In glycolysis, ATP molecules are produced by _____.
Which of these is NOT a product of glycolysis?
In glycolysis, what starts the process of glucose oxidation?
In glycolysis there is a net gain of _____ ATP
Which of the following describes the process of glycolysis?
It represents the first stage in the chemical oxidation of glucose by a cell.
Substrate-level phosphorylation accounts for approximately what percentage of the ATP formed by the reactions of glycolysis?
In addition to ATP, what are the end products of glycolysis?
NADH and pyruvate
In glycolysis, for each molecule of glucose oxidized to pyruvate
two molecules of ATP are used and four molecules of ATP are produced.
A molecule that is phosphorylated
has an increased chemical potential energy; it is primed to do cellular work.
Which kind of metabolic poison would most directly interfere with glycolysis?
an agent that closely mimics the structure of glucose but is not metabolized
