The Student and Tutor reviewed foundational concepts in cell biology, including cell types, genetic material, and the hierarchy of biological organization. The session then focused on the detailed structure and components of the plasma membrane, exploring its lipid bilayer composition and embedded proteins. They further investigated passive transport mechanisms, differentiating between simple and facilitated diffusion, and discussed the general principles that distinguish passive from active transport.

The Student and Tutor reviewed key Biology concepts from previous sessions, including posterior pituitary hormones and the distinction between prokaryotic and eukaryotic cells. The session then moved on to detailed discussions about human genetic material, sex determination, and the fundamental processes of transcription and translation within cells. The Tutor plans to use figures and examples in the next class to further clarify the five kingdoms of life.

The Student and Tutor reviewed key concepts of the endocrine system, including the adrenal glands, thymus gland, and a detailed exploration of the pituitary gland's hormones and their functions. They also introduced cell biology, covering the five-kingdom classification and the fundamental differences between prokaryotic and eukaryotic cells, including their internal structures and functions. The next session will continue with cell division.

The Tutor and Student reviewed various endocrine glands, including the thyroid, parathyroid, adrenal, and thymus glands, detailing their hormones and functions. They also began discussing the pituitary gland, covering its anterior lobe hormones and their roles. Future sessions will cover posterior pituitary hormones, the pineal gland, and related disorders.

The Student began by reviewing the previous session's topics on chemical messengers, endocrine/exocrine glands, and the role of insulin and glucagon in blood glucose regulation, including the two types of diabetes. The Tutor then introduced the thyroid and parathyroid glands, explaining their hormones (T3, T4, calcitonin, PTH) and their roles in growth, metabolism, and calcium homeostasis. They concluded by discussing the multi-organ Vitamin D3 activation pathway and its critical link to calcium absorption. The next session will cover the remaining hormones.

The session covered the endocrine system, focusing on hormones as chemical messengers and the functions of major endocrine glands. The student and tutor discussed glucose homeostasis, detailing the roles of insulin and glucagon, and differentiating between Type 1 and Type 2 diabetes mellitus based on insulin levels and receptor function. The next session will explore intracellular receptors in more detail.
