Answer:
False.
Explanation:
Neurotransmitter release occurs from the nervous terminal or varicosities in the neuronal axon. When an action potential reaches the nervous terminal, the neurotransmitter is released by exocytose. The molecule binds to its receptor in the postsynaptic neuron, triggering an answer. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic response. To stop this process the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:
• Enzymatic degradation/deactivation: There are specific enzymes in the synaptic space, which are in charge of inactivating the neurotransmitter by breaking or degrading it. The enzyme acetylcholinesterase prevents ACh from continuing to stimulate contraction.
• Reuptake: Receptors located in the presynaptic membrane can capture de molecule to store it back in new vesicles for posterior use. These transporters are active transport proteins that easily recognize the neurotransmitter.
B as asexual reproduction the offspring is genetically identical to the parent
Answer:
enzymes
Explanation:
Enzymes are organic catalysts which are protein in nature. The enzyme proteases found in baby food aid in break down of peptides into amino acids in the stomach. Extracellular enzymes are engineered outside the cells that produce them e.g., proteases. The proteases break down milk proteins into amino acids that are easily assimilated into the system reducing chances of babies developing allergies to milk. Particular proteases break down specific allergenic proteins that can cause allergic in hypoallergenic food .
A vacuole takes up the majority of the space in a mature plant cell, providing structure. Kind of like a full water balloon. This is why plants stand up straight.
With the exception of the three irreversible events in glycolysis, gluconeogenesis utilizes the same enzyme processes as glycolysis.
Glycolysis & Gluconeogenesis:
- In contrast to gluconeogenesis, which is crucial for sustaining blood glucose levels during hunger, glycolysis is a catabolic process that hydrolyzes glucose to produce energy and biosynthetic intermediates.
- In the catabolic route of glycolysis, glucose is converted to pyruvate. The anabolic route known as glucose conduction produces glucose from non-carbohydrate sources like glycerol and glucogenic peptides. Pyruvate turns into glucose during the process of gluconeogenesis.
- The general consensus would be that glycolysis and gluconeogenesis don't happen at the same time within similar cells, instead, that metabolic circumstances or allosteric effectors that drive flux along one pathway repress flow in the other direction.
Original question:
1) Gluconeogenesis uses the same enzymatic reactions of glycolysis except for the ________.
A) pyruvate kinase catalyzed step
B) 4 irreversible reactions in glycolysis
C) 3 irreversible reactions in glycolysis
D) 2 irreversible reactions in glycolysis
