This MCAT Basics podcast covers biological membranes. First, the podcast introduces a few topics regarding membranes: what they are, how they are formed, their presence in the cell, and cell-to-cell junctions. Second, it addresses transport through the membrane, including simple diffusion, active vs. passive transport, and transport membrane proteins. Next, the discussion moves to membrane proteins, including receptors, transporters, and the differences between integral, peripheral, and lipid-anchored proteins. Finally, the podcast covers membrane dynamics, such as endocytosis and the transmembrane system, and discusses membrane potential.

In this episode, we’ll talk about ATP or adenosine triphosphate. We will begin with a detailed examination of ATP's structure and composition as a nucleotide, followed by an explanation of the metabolic pathways involved in its production—both aerobic and anaerobic. We will also cover the pivotal process of ATP hydrolysis, emphasizing its energy release and crucial role in various cellular processes, including the sodium-potassium pump and protein phosphorylation.

Additionally, we will address the limitations of ATP supplementation and the broader implications of ATP in biological transport and biosynthesis processes. This episode promises to provide a clear and thorough understanding of ATP's essential functions, ensuring you are well-prepared for your MCAT studies.

In this episode, we explore the topic of intelligence, which is primarily featured in the psychology and sociology section of the MCAT.

We cover several key theories, including entity vs. incremental theory, general intelligence theory, two-factor theory, multiple intelligences theory, Triarchic theory, CHC theory, and biological theories. Additionally, we examine the nature vs. nurture debate on hereditary intelligence factors and discuss how intelligence is measured.
