Cell Membranes

015 - Cell Membranes Paul Andersen explains how cells are selectively permeable with the help of their cell membrane. The main constituents of the cell membrane, including cholesterol, glycolipids, glycoproteins, phospholipids, and proteins are included. The fluid mosaic model is also illustrated. The cell wall in plants, bacteria, and fungi is also discussed.

Transport Across Cell Membranes

016 - Transport Across Cell Membranes Paul Andersen describes how cells move materials across the cell membrane. All movement can be classified as passive or active. Passive transport, like diffusion, requires no energy as particles move along their gradient. Active transport requires additional energy as particles move against their gradient. Specific examples, like GLUT and the Na/K pump are included. Do you speak another language? Help me translate my videos: www.bozemanscience.com/translations/ All ...

Compartmentalization

017 - Compartmentalization Paul Andersen explains how eukaryotic cells use compartmentalization to increase the surface area and level of specialization within the cell. Prokaryotic and eukaryotic cells are compared and contrasted. The role of both the mitochodria and endoplasmic reticulum are discussed. Do you speak another language?

Positive And Negative Feedback Loops

018 - Positive and Negative Feedback Loops Paul Andersen explains how feedback loops allow living organisms to maintain homeostasis. He uses thermoregulation in mammals to explain how a negative feedback loop functions. He uses fruit ripening to explain how a positive feedback loop functions. He also explains what can happen when a feedback look is altered. Diabetes mellitus is caused by an alteration in the blood glucose feedback loop. Do you speak another language? Help me ...

Response To External Environments

019 - Response to External Environments Paul Andersen explains how organisms respond to the external environment. He begins with a discussion of behavioral responses like hibernation and migration. He ends with a discussion of physiological responses like shivering and sweating. Organisms respond to their environment in order to maintain homeostasis. Do you speak another language?

Biotic And Abiotic Factors

020 - Biotic and Abiotic Factors Paul Andersen differentiates between biotic and abiotic factors. He explains how both abiotic and biotic factors can affect organisms at the level of the cell, the population and even the ecosystem. The complexities of biofilms, predator-prey relationships, and food webs are given as illustrative examples. Do you speak another language?

Homeostatic Evolution

021 - Homeostatic Mechanisms Reflect Evolution - Paul Andersen shows how homeostasis reflects of evolution through time. The endocrine system shows continuity through flatworms, earthworms and vertebrates. However the respiratory system shows change as organisms move onto land. The importance of the Tiktaalik fossil as a transitional fossil is emphasized. Do you speak another language?
