Objectives: Outline the role played by ATP in powering cellular activity.
Describe the mechanism of ATP formation.
Outline the importance of redox reactions in cellular energy generation.
Outline the role of NADH in energy transfer.
The cell needs energy to do [blank_start]work[blank_end]. [blank_start]Energy coupling[blank_end] allows exergonic processes (which [blank_start]release[blank_end] energy) to be coupled with endergonic processes (which [blank_start]absorb[blank_end] energy) so that every necessary process is facilitated.
Respuesta
work
Energy coupling
release
absorb
Pregunta 2
Pregunta
Which process is ATP NOT involved in?
Respuesta
Neurotransmission
RNA synthesis
Transport
Cell linking
Pregunta 3
Pregunta
Select the equation which BEST outlines the exergonic process of ATP hydrolysis.
Respuesta
ATP → ADP + Phosphate group + Energy
ATP → ADP + PO3 + ATP
ADP + Phosphate group + Energy → ATP
ADP → ATP
Pregunta 4
Pregunta
ATP hydrolysis does not change the energy of a system, but rather creates free energy for another process.
Respuesta
True
False
Pregunta 5
Pregunta
ATP phosphorylates molecules which would not normally react and allows endergonic processes to occur.
Respuesta
True
False
Pregunta 6
Pregunta
ATP hydrolysis cools the surrounding environment.
Respuesta
True
False
Pregunta 7
Pregunta
ATP is recyclable.
Respuesta
True
False
Pregunta 8
Pregunta
Which statement about the ATP cycle is CORRECT?
Respuesta
ATP hydrolysis forms ADP and a phosphate group, as well as producing free energy for endergonic processes
ATP will readily reform from ADP and a phosphate group while free floating in the cytoplasm.
Pregunta 9
Pregunta
Fermentation is a [blank_start]catabolic[blank_end] process to attain chemical energy from food [blank_start]anaerobically[blank_end].
Cellular respiration is a catabolic process to attain [blank_start]chemical energy[blank_end] from food [blank_start]aerobically[blank_end], mainly from [blank_start]glucose[blank_end] in starch and carbohydrates.
Respuesta
catabolic
anabolic
chemical energy
mechanical energy
aerobically
anaerobically
glucose
