Oxidation vs. Reduction, What are Oxidation and Reduction Reactions in Everyday Life?

Oxidation and Reduction (Redox) Reactions Step-by-Step Example

When glucose donates electrons to NAD+ creating NADH, the glucose molecule becomes:a) Hydrolyzed.b) Oxidized.c) Neutral.d) Reduced.

Electron carrier molecules

 No. During oxidation, electrons and hydrogen are removed. 

 No. However, you are partly right. Oxygen is reduced. 

 No. The carbon in carbon dioxide is already oxidized. 

 No. However, you are partly right. Glucose is oxidized. 

Consider what is produced at the end of the electron transport chain.

In the overall process of glycolysis and cellular respiration, __________ is oxidized and __________ is reduced.

What is the oxidizing agent in the following reaction?
Pyruvate+NADH+H+→Lactate+NAD+
a. oxygen
b. NADH
c. lactate
d. pyruvate

Redox Reactions: Crash Course Chemistry #10

8.2 Electron Carriers

 No. Oxidation changes the shape of the molecule; a change in shape does not cause oxidation. 

 No. Oxidation involves changes in electrons. 

Recall that oxidation is the opposite of reduction.

A molecule becomes more oxidized when it __________.

GCSE Chemistry - Oxidation and Reduction - Redox Reactions #39 (Higher Tier)

 oxygen is so abundant in the atmosphere 

 No. Oxygen does make up 22% of the atmosphere, but this does not determine its redox properties. 

 oxygen gas is composed of two atoms of oxygen 

 No. Oxygen gas is composed of two atoms of oxygen, but its strength as an oxidizing agent is more dependent on the properties of the oxygen atom. 

 No. Atoms with double bonds are not necessarily strong oxidizing agents. 

 oxygen acts as the final electron acceptor in cellular respiration 

 No. It is the other way around&mdash;oxygen acts as the final electron acceptor in cellular respiration because it is such a strong oxidizing agent. 

 the oxygen atom is very electronegative 

Consider the properties of the oxygen atom with respect to electrons.

Oxygen gas (O2) is one of the strongest oxidizing agents known. The explanation for this is that __________.

 No. Carbon dioxide is produced as a by-product of the oxidation of glucose. 

 No. Water is the product of the reduction reaction. 

 No. Glucose is oxidized, and carbon dioxide is the product of this oxidation. 

Consider which molecules are gaining electrons and which are losing electrons.

During the reaction C6H12O6 + 6 O2 &rarr; 6 CO2 + 6 H2O, which compound is reduced as a result of the reaction?
