From all of the things to choose the one that isnt negative in its way is B. releases carbon
Answer:
1. Acetylcholine binds to receptors on the motor end plate
2. Ligand-gated channels open leading to depolarization
3. End plate potential triggers an action potential
4. Transverse tubules convey action potentials into the interior of the muscle fiber
5. Calcium is released from the sarcoplasmic reticulum
6. Calcium ions bind to troponin, which then moves tropomyosin
Explanation:
Acetylcholine (ACh) is a signaling molecule (neurotransmitter) that binds to receptors on muscle cells. This binding triggers the opening of ligand-gated sodium channels, thereby ions enter into muscle cells, which causes the depolarization of the sarcolemma and thus promotes the release of Ca2+ ions from the sarcoplasmic reticulum. The myoneural junction, also known as the motor endplate, is the site of synaptic contact between a motor axon and a skeletal muscle fiber. The endplate potential is the voltage that produces the depolarization of muscle fibers when ACh molecules bind to their receptors in the cell membrane. This depolarization spreads in the sarcolemma through transverse tubules (T tubules) and thus generates an action potential. Finally, this action potential induces the release of Ca2+ in the sarcoplasmic reticulum, which activates troponin protein and induces muscle contraction.
You are familiar with the electron transport system in photosynthesis
that takes light energy and converts it to chemical bond energy in the
form of ATP and NADPH. This electron transport chain in cellular
respiration will take the energy stored in NADH and FADH2
during the Krebs cycle and convert it to chemical bond energy in the
form of ATP. In eukaryotes, this reaction takes place on the inner
mitochondrial membrane, as is shown in Figure 4.26. Prokaryotes that
undergo aerobic respiration also have an electron transport chain
located within their plasma membrane, which may be highly folded similar
to the inner membrane of the mitochondrion. Thats the answer my friend hope it helps
