Cellular Respiration and Enzymes

The proton gradient generated by the electron transport chain drives the synthesis of ATP through ATP synthase. As protons flow down the gradient, they pass through ATP synthase, causing it to rotate and synthesize ATP from ADP and inorganic phosphate.

Pyruvate dehydrogenase is not a component of the electron transport chain. It is an enzyme involved in the conversion of pyruvate to acetyl-CoA, which enters the citric acid cycle.

Anaerobic metabolism, specifically the breakdown of glucose without the use of oxygen, is the primary energy source for short-duration, high-intensity exercise.

Glycogenolysis is the process by which glycogen, a stored form of glucose in muscle and liver cells, is broken down into glucose for energy production.

Lipolysis is the process by which triglycerides, stored in adipose tissue, are broken down into glycerol and fatty acids for energy production.

Proteolysis is the process by which proteins are broken down into amino acids for energy production.

Glycolysis is the process by which glucose is broken down into pyruvate for energy production.

The pyruvate dehydrogenase complex is a series of enzymes that convert pyruvate into acetyl-CoA, which is then used in the citric acid cycle for energy production.

The citric acid cycle, also known as the Krebs cycle, is a series of chemical reactions that convert acetyl-CoA into ATP, the body's primary energy currency.

Cellular respiration is the process by which organisms obtain energy from food.

Monitoring cell density, pH, and dissolved oxygen levels is essential during upstream processing to assess cell growth, metabolism, and overall health of the culture, allowing for timely adjustments to maintain optimal growth conditions.

Monitoring oxygen consumption rate, carbon dioxide production rate, and glucose consumption rate provides insights into the metabolic activity of cells during upstream processing, allowing for assessment of cell viability, energy production, and overall culture health.

Hydrolysis is a Phase I metabolism reaction that involves the cleavage of chemical bonds by water molecules.

C3 convertase is an enzyme complex that cleaves C3 into C3a and C3b, initiating the formation of the membrane attack complex.

Enzymatic biosensors utilize the catalytic activity of enzymes to convert a specific biological molecule into a detectable signal. The enzyme-substrate reaction generates a product that can be measured, either directly or indirectly.
