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.
Responda
work
Energy coupling
release
absorb
Questão 2
Questão
Which process is ATP NOT involved in?
Responda
Neurotransmission
RNA synthesis
Transport
Cell linking
Questão 3
Questão
Select the equation which BEST outlines the exergonic process of ATP hydrolysis.
Responda
ATP → ADP + Phosphate group + Energy
ATP → ADP + PO3 + ATP
ADP + Phosphate group + Energy → ATP
ADP → ATP
Questão 4
Questão
ATP hydrolysis does not change the energy of a system, but rather creates free energy for another process.
Responda
True
False
Questão 5
Questão
ATP phosphorylates molecules which would not normally react and allows endergonic processes to occur.
Responda
True
False
Questão 6
Questão
ATP hydrolysis cools the surrounding environment.
Responda
True
False
Questão 7
Questão
ATP is recyclable.
Responda
True
False
Questão 8
Questão
Which statement about the ATP cycle is CORRECT?
Responda
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.
Questão 9
Questão
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.
Responda
catabolic
anabolic
chemical energy
mechanical energy
aerobically
anaerobically
glucose
Questão 10
Questão
Which of the following statements about cellular respiration is CORRECT?
Responda
Cellular respiration harvests energy from C-H bonds by transferring the electrons to O2.
Cellular respiration harvests energy from C-H bonds and transfers the electrons to O2.
Cellular respiration harvests energy from C-H bonds by transferring the electrons to an electron carrier like NAD.
Questão 11
Questão
Cellular respiration releases a large amount of energy in a process similar to simple combustion.
Responda
True
False
Questão 12
Questão
Cellular respiration harvests usable energy in a series of controlled steps.
Responda
True
False
