Study Notes

Transport Mechanisms

  • In renal tubules, glucose and sodium ions are transported via a secondary active transport mechanism, where the energy from sodium transport is used to drive glucose transport.

Eye Physiology

  • The primary factor that plays the most important role in focusing in the eye is the shape of the lens.

Transport Types

  • Electrogenic transport is a type of transport that generates an electric potential difference across the membrane, making it rheogenic.

Energy Transfer

  • Charge carriers play a crucial role in energy transfer, and the essential factor in this process is the energy-rich molecules of NADH and FADH2.

Cellular Respiration

  • The electron transport chain is located in the mitochondrial inner membrane.

Therapeutic Applications

  • Liposomes are more desirable particles for therapeutic application due to their ability to encapsulate and deliver therapeutic agents.

Enzyme Regulation

  • Coenzyme A is a product inhibitor of citrate synthase, regulating the citric acid cycle.

Metabolic Disorders

  • The probable metabolic defect in gout is the impaired metabolism of uric acid, leading to its accumulation in joints.

Electron Carriers

  • Cytochrome b contains a bound NADH, playing a crucial role in the electron transport chain.


  • Folate is a coenzyme categorized as part of paternal genome imprinting, influencing gene expression.

Cellular Respiration

  • For each FADH2, 1.5 ATPs are formed in mitochondria.

Membrane Physiology

  • The parameter 'r', known as the Donnan ratio, determines the distribution of ions across a membrane.

Test your knowledge on various topics such as cytochromes, coenzymes, genome imprinting, and ATP production in mitochondria. Questions include identifying components and understanding key concepts in biochemistry and genetics.
