Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to produce needed energy from nutrients. These processes help keep the Earth in balance by breaking down the food that photosynthesis produces.

Part of the "Visualizing Cell Processes" series. Includes the following modules on photosynthesis: "Chloroplast Structure," "Light Trapping by Chlorophyll," "Light–Dependent Reactions of Photosynthesis," and "The Light–Independent Reactions of Photosynthesis." Includes the following modules on cellular respiration: "Glycolysis and Fermentation," "Mitochondrion Structure," "Aerobic Respiration," "Krebs Cycle," "Electron Transport Chain," and "ATP synthesis."
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the biological processes involved in cellular respiration and how these processes provide energy to living things. Part of the Science Video Vocab series.
Explains the scientific concepts of photosynthesis, respiration, and enzymes. Laboratory experiments demonstrate: the rate of photosynthesis in greenhouse plants; the amount of oxygen used by the body during respiration at varying speeds; and the reaction times of different enzymes.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. It's the night of the rock lovers' annual Granite Awards, and Arnold is about to become the first kid ever to win the coveted Rocky Award. He's so excited; all he's been able to eat for weeks are "Seaweedies.” When he arrives for the big event, he’s nervous and orange. Once the class determines that the orange isn't on Arnold's skin, they shrink down to explore what's underneath. They discover that his whole body is made of living cells, and they're all orange.
New research finds that hummingbird species living at high altitudes have evolved hemoglobin with enhanced oxygen-binding properties so they can thrive in oxygen-poor environments. A team of scientists demonstrate how hummingbirds adapt to life at high altitudes.
Anna was born with a sweet tooth, and as a young woman, she created a successful business using it. Her delicious jams and jellies gave pleasure to many, but did they also cause harm? Explores the way the human body processes food and how its long-term growth and development are shaped by eating habits. Illustrating cellular aging and its relationship to AGEs, or advanced glycation end products, a connection is drawn between the bacteria an infant must consume to build a healthy immune system and the bacteria that consume the body at death. As Anna's life draws to a close, viewers will understand that "dust to dust" is a cycle in which humans take an active part--every time they sit down to a meal.
What happens when an organism can't perform aerobic cellular respiration because oxygen isn't available? Explore fermentation with Pinky and Petunia. This episode focuses on alcoholic fermentation and lactic acid fermentation. Part of "The Amoeba Sisters" series.
Colony formation on semi-solid medium is basic characteristic of many different bacteria and an important property for microbiologists. These models illustrate the different types of colonies formed, what a colony reflects at the cellular level, how microbiologists obtain isolated colonies, and what happens when cells swarm instead of forming colonies.

The story of the coelacanth shows how natural history collections can yield answers and inspire questions for hundreds of years. Ichthyology Curator Melanie L. J. Stiassny presents the ultimate fish tale and offers a primer on specimen prep. Part of the "Shelf Life" series.
Updates the five kingdoms classification scheme with the latest understanding of life's organization based on DNA, fossil, and biochemical evidence, reorganizing all life into three great branches: Archaea, Bacteria, and Eucarya. Shows concise animations and superb microscope footage of primitive cells.
Biology is the study of life. It encompasses the cellular basis of living things, the energy that underlies the activities of life, and the genetic basis for inheritance in organisms. Topics covered include the smallest components of living things: atoms, molecules, organelles, and cells. Part of the "Biology" series.
Part of the "The Biology Classics" series. Hydra is a genus of simple fresh-water animals possessing radial symmetry. Observes feeding behavior of hydra, shows detailed microscopy of stinging cells used in capturing prey, and reviews two digestive processes: cellular and extracellular. Also covers locomotion, reproduction by budding, the development of sex organs, and symbiotic guests, both external and internal.
Are humans the accidental products of an uncaring universe? Or are they the beneficiaries of a cosmic order that was planned beforehand to help them flourish? This documentary explores growing evidence from physics, chemistry, biology, and related fields that our universe was designed for large multi-cellular beings like ourselves. Geneticist and author Michael Denton investigates the special properties of carbon, water, and oxygen that make human life and the life of other organisms possible.
Part of the "Inside the Living Cell" series. Illustrates the mechanisms of photosynthesis and cellular respiration. Introduces adenosine triphosphate, or ATP, the universal energy carrier molecules that supply energy-hungry reactions. Also outlines the structure and function of chloroplasts and mitochondria, energy transforming organelles. Overviews ATP and chemical energy, mitochondria, aerobic respiration, chloroplasts, and the reactions of photosynthesis.
No organism lives forever. The length of time animals and humans live is influenced by their genes. Scientists have made astonishing discoveries concerning the role of genetics in determining life span, and this holds promise of extending the lives of animals and humans. Explains genetics, DNA, and genetic theories of aging. Illustrates the genetic processes behind cellular aging, and shows how genes affect life span. Discover the reasons why cells age and why a certain enzyme can effectively turn back the hands of our "biological clock."
Presents a brief history of what new information caused the classification of living things to evolve from the original two kingdom classification of animals and plants by Linnaeus in the 18th century to the present-day six kingdoms: Animal, Plant, Fungi, Protista, Eubacteria, and Archaebacteria. Discusses three of the six kingdoms: Protista, Eubacteria, and Archaebacteria. Also, presents the hierarchical classification from kingdom to species. Because viruses do not have the capability of an independent cellular life, they are included in neither the kingdom nor domain classifications.
Human beings, like every living organism, are driven by two inherent needs: to survive, and ultimately, to reproduce. To accomplish the goals of survival and reproduction, we have inherited bodies crafted by evolution so that every individual human organism is an organic super factory, a living machine made up of systems that process fuel, build products, repair damage, expel waste, and defend against invaders. Introduces the complex physiological systems of the human body: muscular movement, digestion, circulation, respiration, nerves, glands, immunity, and reproduction. Also, illustrates and explains the cellular basis of life and the importance of carbon in organic chemistry.
With support from the National Science Foundation, Liangfang Zhang and his team at UC-San Diego have created a nanosponge to combat drug-resistant infections, such as those caused by Methicillin-resistant Staphylococcus aureus (MRSA). The nanosponge, made from biocompatible, biodegradable polymer nanoparticles, is camouflaged with a red blood cell membrane. It circulates in the bloodstream, absorbing the toxins produced by infection. Once the nanosponges are fully loaded with toxins, they are safely disposed of by the liver. They are designed to work with any type of infection or poison that attacks the cellular membrane. Part of the National Science Foundation Series “Science Nation.”
