Answer:
CH4
Explanation:
Combining hydrogen and carbon produces a group of organic compounds called hydrocarbons. Depending on the specific molecular formula, there can be many different types of hydrocarbons, such as the fuels propane and octane. The simplest hydrocarbon is methane, which has the chemical formula CH4.
I believe it is the second one not 100% sure so don't blame me if you fail.
The process of Glycolysis breaks one 6-carbon glucose molecule into two 3-carbon molecules, 2 NADH AND 2ATP molecules.
<h3>What is Glycolysis?</h3>
- Glycolysis is the metabolic process that converts glucose into pyruvic acid to produce energy.
- The process takes place in the cytoplasm of a cell and does not require oxygen.
- It occurs in both aerobic and anaerobic organisms.
- Glycolysis is the primary step of cellular respiration, which occurs in all organisms.
- Six enzymes are involved in the process.
- The end product of the reaction includes 2 pyruvate, 2 ATP, and 2 NADH molecules.

Answer:
The correct order of events is:
C) Nicotine binds to the transmembrane protein that normally binds the neurotransmitter acetylcholine.
A) The acetylcholine receptor is an ion channel, and when a ligand binds, the ion channel opens.
B) An influx of ions carries the signal to the reward areas of the brain.
D) The signal causes release of dopamine in the brain, which causes good feelings.
E) Nicotine is quickly eliminated from the body (causing cravings for more cigarettes to produce good feelings).
Explanation:
Nicotine acts on acetyl cholinergic receptors that are located in membranes of the midbrain neurons. Nicotine can activate those receptors or block them more efficiently than acetylcholine. Stimulation of nicotinic receptors leads to an increase in ions flow that reaches the brain and causes dopamine release in the nucleus accumbens through axonal prolongations of the dopaminergic pathway. This response is responsible for the smoker´s recompense sensation.
The dopaminergic pathway is the most important way in the process of nicotine dependence and addiction to the drug.
