Module 3 (Quiz) - What is metabolic energy ultimately released as?
Heat
Module 3 (Quiz) - Electrons transferred through the process of respiration are eventually donated to oxygen, resulting in its reduction to form:
Water
Module 3 (Quiz) - Metabolism is basically a collection of simple chemical reactions, each _________ by an enzyme.
Catalysed
Module 3 (Quiz) - True or false: The Calvin Cycle is a main stage in respiration
False (photosynthesis)
Module 3 (Quiz) - Glycolosis may occur in the first part of the fermentation of ________ by yeasts to lactate (where there is an absence of oxygen)
Ethanol
Module 3 (Quiz) - What happens to electrons when oxidation occurs?
They are lost

Free energy
Module 3 (Quiz) - When matter is recycled through a system, there is also a flow of:
a) Electrons
b) Energy
Energy
Module 3 (Quiz) - What is acetaldehyde?
An intermediate compound formed during the process of ethanol fermentation
Module 3 (Quiz) - What is the final electron acceptor of the TCA (The Citric Acid) cycle?
Oxygen
Module 3 (Quiz) - In each turn of TCA cycle, how many molecules the following are regenerated:
i) ATP
ii) NADH
iii) FADH2
i) 1
ii) 3
iii) 1
Module 3 (Quiz) - Which 2-carbon molecule enters the TCA cycle?
Acetyl CoA
Module 3 (Quiz) - What do the NADH and FADH2 produced during the TCA cycle do?
Transport electrons
Module 3 (Quiz) - The final electron transport chain in the process of respiration consists of a series of proteins located:
In the inner mitochondrial membrane
Module 3 (Quiz) - The final stage of respiration is the process of ATP synthesis by what?
Oxidative Phosphorlyation
Module 3 (Quiz) - What is the name of the membrane protein that allows protons to flow back into the mitochondrial matrix?
ATP synthase
Module 3 (Quiz) - What does potential energy do at the end of respiration?
It is an electrochemical gradient that fuels the activity of ATP synthase protein
Module 3 (Quiz) - Why is the electrochemical gradient that moves across the mitochondrial membrane called as such?
Because +ve charges are moved, and the chemical H is also moved
Module 3 (Quiz) - How many ATP molecules may be produced during oxidative phosphorylation:
26-28
Module 3 (Quiz) - What is the role of the electron transport chain in the mitochondrial membrane?
to set up an electrochemical gradient across the mitochondrial membrane
Module 3 (Quiz) - Most of the carbon dioxide we breathe out has been produced by the conversion of:
pyruvate to acetyl CoA
