The correct options to fill in the gaps are:
- ADP; NADH, and electron transport chain
- alcohol fermentation; lactic acid fermentation; acetaldehyde; NADH; and NAD+
<h3>What is the role of NAD+ in glycolysis?</h3>
NAD+ serves as an electron acceptor in glycolysis. It accepts two electrons to become reduced to NADH + H+.
NAD+ is a limiting factor in glycolysis. In the absence of ADP, the conversion of NADH to NAD+ via the electron transport chain is prevented from happening.
In eukaryotes, the hydrogen atoms of the molecules mentioned in are transferred to certain organic molecules in one of two methods: alcohol fermentation as can occur in yeast and lactic acid fermentation as can occur in human cells. In the process mentioned in, the hydrogen atoms are passed to acetaldehyde, which is then converted to a molecule of ethanol. During this a molecule of NADH is oxidized to a molecule of NAD+, which allows glycolysis to continue on.
In conclusion, NAD+ concentration is limiting to glycolysis.

The link where the action
potential of the nerve that meets muscle and causes it to contraction is where excitation-contraction coupling occurs. The T_tubules the
invaginate into the sarcolemma of the muscle cells are the ones that carry the excitation into the muscles. Its depolarization
causes the lateral sacs of the sarcoplasmic reticulum to release ca2+
ions. The ca2+ then bind into their site on troponin and causes the tropomyosin to shift and allow actin to expose
the binding site in which myosin head
will bind and form a cross bridge that is
important in the contraction of the muscle.
