The molecule that serves as the common branch point for either the anaerobic or aerobic pathway is pyruvate. Depending on the availability of oxygen, pyruvate can either be converted into acetyl-CoA to enter the aerobic pathway (Krebs cycle or citric acid cycle) or undergo fermentation in the absence of oxygen.

A complete left bundle branch block (LBBB) occurs when there is a blockage in the electrical pathway (bundle branch) that carries signals to the left side of the heart. This can cause a delay in the electrical signals reaching the left ventricle, leading to changes in the appearance of the ECG waveforms. It may indicate an underlying heart condition and should be evaluated by a healthcare provider.
The carbohydrate substrate described is glycogen. It is a highly branched molecule composed of glucose units in chains of about 10-20 glucose units per branch. Glycogen serves as a storage form of energy in animals, particularly in liver and muscle cells.
The ramus intermedius is an anatomical variation of the coronary artery pattern, where a third branch arises from the left anterior descending artery. This variant can increase the risk of developing coronary artery disease, as it can provide an additional pathway for blockages to occur. It is important for healthcare providers to be aware of this variation when assessing and treating patients with heart conditions.
A DNA molecule consists of two strands that are made up of nucleotides. Each nucleotide is composed of a sugar molecule, a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The two strands are connected by hydrogen bonds between complementary nitrogenous bases.
Glycolysis is a metabolic pathway in the body, and is studied in most basic biochemistry classes.

In a parallel circuit, each branch has its own pathway for current to flow. A switch placed in one branch of the circuit can control the flow of current through that specific branch only, without affecting the other branches. When the switch is closed, it allows current to flow through that branch; when it's open, it blocks the flow of current.
In patients with right bundle branch block (RBBB), the nerve impulse is conducted slowly or not at all. The right ventricle finally receives the impulse through muscle-to-muscle spread, outside the regular nerve pathway.
A complete left bundle branch block (LBBB) occurs when there is a blockage in the electrical pathway (bundle branch) that carries signals to the left side of the heart. This can cause a delay in the electrical signals reaching the left ventricle, leading to changes in the appearance of the ECG waveforms. It may indicate an underlying heart condition and should be evaluated by a healthcare provider.

The esophagus and trachea both branch off of the pharynx, which is the common pathway for air and food. The esophagus carries food from the mouth to the stomach, while the trachea carries air from the mouth and nose to the lungs.
A parallel circuit consists of multiple pathways for current to flow. Each branch in a parallel circuit provides a separate path for current to travel, allowing for continuity in the circuit even if one path is broken or has higher resistance.
Isobutyl, sec-butyl, and tert-butyl are all types of butyl groups, which are branches of the main carbon chain in a molecule. The main difference between them is the position of the branch on the carbon chain. Isobutyl has a branch on the second carbon atom, sec-butyl has a branch on the second carbon atom as well but it is attached to another carbon atom, and tert-butyl has a branch on the third carbon atom.
The ramus intermedius is an anatomical variation of the coronary artery pattern, where a third branch arises from the left anterior descending artery.

having structure in an organisation - provides a 'pathway' for the chain of command or disciplinary procedure. Chain of command in a bank for example, could be - Chairman, Regional manager, Branch Manager, Investments Manager, Cashier. Disciplinary chain could be - the above list in reverse.
The spinal cord is like the main road through a city, it provides a pathway down the body for the other nerves to branch off and reach muscles, tissues, organs etc. and for these nerves to join back up and return to the brain.
