explosive
endergonic
exergonic
exergonic
endergonic
2.
Which neuronal/synaptic event is NOT correctly paired with the location that it takes place?
Number 5: Vesicles containing acetylcholine fuse with the presynaptic membrane.
Number 6: Acetylcholine molecules move across the synaptic cleft.
Number 1: Action potential arrives at the axon terminal.
Number 3: Voltage-gated calcium channels open.
3.
Chemical bonds in carbohydrates (i.e., glucose) and fats, have:
small amount of kinetic energy
large amount of potential energy
small amount of potential energy
no potential or kinetic energy
4.
The figure below depicts a series of metabolic reactions resulting in the conversion of molecule A to molecule E. It also illustrates the changes of free energy that occur at each step in the pathway.
Question: The smallest change in free energy takes place when:
B is converted to C
C is converted to D
A is converted to B
D is converted to E
explosive
endergonic
exergonic
exergonic
endergonic
Explanation / Answer
1) protein biosynthesis endergonic process where it consumes the energy for activation of amino acids.
2) voltage gated Calcium channels open
3) potential energy are of different types and they have significant role in biological systems.and potential energy is stored in bonds connecting atoms in a molecules.
Carbohydrates especially glucose and fats they contain large amount of potential energy.
Among this glucose is a bio molecule which provides continuous supply of energy for cells
