Redox Reactions Example 1

Electron carrier molecules | Biomolecules | MCAT | Khan Academy

Alkene Redox Reactions: Crash Course Organic Chemistry #17

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)

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.

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?

8.3 Oxidation and Reduction of Electron Carriers in Photosynthesis

A Level Chemistry Revision "Introduction to Redox Reactions"

Redox Reactions

Oxidation-Reduction Reactions

Electron Carriers: NADH & FADH2

NAD+ and NADH Leaving Cert Biology

An electron carrier before it harvests energy from glucose molecules in a series of gradual steps is:a) Pyruvate.b) AMP.c) ATP.d) NAD+.e) NADH.

Draw a chemical equation to represent the redox reaction that occurs when methane (CH4) burns in the presence of oxygen (O2). Identify the reactant that is reduced and the reactant that is oxidized. Of the four molecules that should be in your equation, point out the one that has bonds with the highest potential energy.

USMLE Step 1 - Lesson 55 - Carriers, Electron Acceptors, and Hexokinase vs Glucokinase

Oxidation is the _________________________, and reduction is the _________________________.a) Gain of electrons; Loss of electrons.b) Gain of protons; Loss of protons.&nbsp;c) &nbsp;Loss of electrons; Gain of electrons.d) &nbsp;Gain of oxygen; Loss of oxygen.
