True or False: The Δ G value for a particular reaction is -78kJ/mol. This value indicates the reaction is
spontaneous.
- correct answer true
True or false: A biochemical metabolic pathway is a single reaction that converts starting material into
products.
- correct answer false
Three ATP molecules are used in the energy-investing stage of glycolysis.
- correct answer false
The citric acid cycle occurs in the presence of oxygen.
- correct answer true
The β -oxidation pathway only degrades odd-numbered fatty acids.
- correct answer true

- correct answer - Hexokinase
In the last reaction of glycolysis, ATP is formed by the direct transfer of a phosphate group from a
metabolite to ADP. This process is referred to as:
