OCR Biology A - 2.1.2 - Biological Molecules Part 5

A-Level PE AQA Diet and Nutrition Part 1

This flashcard deck covers key concepts in diet and nutrition, focusing on topics such as cholesterol, carbohydrates, fats, proteins, and vitamins, as outlined in the A-Level PE AQA curriculum.

USMLE - Metabolism Part 1

Glycolysis is a 10-step metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH. Key regulatory enzymes include hexokinase/glucokinase, phosphofructokinase (PFK), and pyruvate kinase. The pathway splits glucose into two molecules of G3P, which are further processed to generate energy.

USMLE - BioChem Part 2

Histone acetylation relaxes DNA coiling by neutralizing positive charges on histones, reducing their interaction with negatively charged DNA. This opens up chromatin structure, allowing transcription to occur.

USMLE - BioChem Part 1

An autosomal dominant disorder with incomplete penetrance, characterized by hamartomas in the CNS and retina, cutaneous angiofibromas (adenoma sebaceum), ash-leaf spots, seizures, mental retardation, mitral regurgitation, cardiac rhabdomyomas, renal angiomyolipomas, and increased risk of astrocytomas.

USMLE - GI Flashcards Part 10

Courvoisier's sign refers to a palpable, nontender gallbladder in a patient with painless jaundice.

NASM: Chapter 8 - Exercise Metabolism and Bioenergetics

This flashcard set defines metabolism as the sum of chemical reactions that sustain life, and introduces exercise metabolism as the study of energy processes during physical activity. It also explains substrates—the fuel sources for metabolism, such as proteins, fats, and carbohydrates—and describes carbohydrates as key energy-providing organic compounds ultimately broken down into glucose.
