Carbs Lecture 7: Energy Production in a Low Oxygen Environment

These flashcards cover key vocabulary terms and concepts related to energy pathways, metabolism, and the physiological responses to exercise.

Gluconeogenic

Referring to substances like glycerol and pyruvate that can be converted into glucose during gluconeogenesis.

Krebs Cycle

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins.

Anaerobic process

A metabolic process that does not require oxygen, such as glycolysis.

Lactic Acid

A byproduct of anaerobic metabolism when pyruvate is converted due to lack of oxygen.

Pyruvate

A key intermediate in several metabolic pathways, it can be converted to acetyl coenzyme A or be used for gluconeogenesis.

Hemoglobin

A protein in red blood cells that carries oxygen from the lungs to the rest of the body.

Glycolysis

The metabolic pathway that converts glucose into pyruvate while producing ATP.

NADH

Nicotinamide adenine dinucleotide, an electron carrier that is reduced during glycolysis and the Krebs cycle to produce ATP.

Metabolite

Any substance produced during metabolism, often used in biochemical pathways for energy production.

Oxygen Transport

The process of delivering oxygen from the lungs to the tissues via the bloodstream.
