Answer:

A.it pumps hydrogen ions inside the cell

Explanation:

Principally, the main role of electron transport chain is to maintain the electrochemical gradient of hydrogen ions (H+) inside the mitochondrial matrix. This is the last step in aerobic cellular respiration and performs a series of redox reactions. Overall, it allows accumulation of H+ inside the mitchondrial matrix. This increased gradient or accumulation of hydrogen ions (H+) is essential because H+ would accept the electrons producing during the reactions. Without this, the flow of electron will be stopped because of high  gradient, and production of ATP will not happen as well.

Indeed ETC helps in production of ATP but that is not the main function of electron transport chain rather it is a function of mitochondria.

Phoenix [80]

Since the round seed gene is the dominant gene, it follows that, a cross between  a round seed plant and a wrinkled seed plant will lead to only round seed offspring.

<h3>What is genetics?</h3>

Genetics is the science that studies the patterns of inheritance. The unit of inheritance located in the chromosome is called the gene.

Since the gene for having round seeds is dominant over the gene for having wrinkeled seeds, a cross between  a round seed plant and a wrinkled seed plant will lead to only round seed offspring.

crimeas [40]

Energy stored in food can be used by cells to add a phosphate group to ADP to make ATP. This cycling of ATP to ADP occurs in a metabolic process called cellular respiration. phosphate group breaks, and energy is released. ATP becomes ADP, and the cycle of storing and releasing energy continues until the cell dies.

Endocytosis process

The vesicular process involved in the toxin entering the neuron is endocytosis process.

Explanation;
Endocytosis is a vesicular process, that involves capturing a particle or a substance from the outside of a cell by engulfing it with the cell membrane, and bringing it into the cell.
Botulinum toxin binds to the neuronal cell membranes at the nerve terminus and enters the neuron by endocytosis.
