In the Amoeba Sisters video recap on enzymes, key points include that enzymes are biological catalysts that speed up chemical reactions without being consumed in the process. They work by lowering the activation energy needed for reactions, and each enzyme is specific to a particular substrate. Factors such as temperature, pH, and concentration can affect enzyme activity. Additionally, enzymes can be denatured, losing their functionality when conditions are not ideal.

What is a good opening for a closing speech?

An effective opening for a closing speech could be a heartfelt thank you to the audience for their time and attention, followed by a brief recap of the main points discussed during the event. This sets a positive and engaging tone for the conclusion of the speech.


How can avoid stucking hot tube together?

To prevent a hot glue tube from becoming stuck, always recap the tube securely after use and store it in a cool, dry place. Try to avoid leaving the tube lying flat after using it, as this can cause the glue to dry around the cap and nozzle, making it difficult to open. If the tube does become stuck, soaking it in warm, soapy water can help loosen the dried glue and make it easier to open.


What is the purpose of transitions signposts internal previews and internal reviews in a speech?

Transitions, signposts, internal previews, and internal reviews serve to enhance the clarity and flow of a speech. Transitions guide the audience from one idea to the next, while signposts highlight key points, helping listeners follow the structure. Internal previews outline what’s coming next, and internal reviews recap important information, reinforcing understanding and retention. Together, these elements ensure the audience stays engaged and comprehends the main messages effectively.


A semi-detailed lesson plan in respiratory system and it's major parts?

Introduction: Start by discussing the importance of the respiratory system in the body and its role in oxygenating the blood and removing carbon dioxide. Major parts of the respiratory system: Explain the key components such as the nasal cavity, trachea, lungs, diaphragm, bronchi, and alveoli. Discuss their functions and how they work together to facilitate breathing. Demonstration: Show a model or diagram of the respiratory system and explain how air flows through each of the major parts during inhalation and exhalation. Activity: Engage students in a breathing exercise to demonstrate the movement of the diaphragm and expansion of the chest cavity during inhalation. Recap and assessment: Review the major parts of the respiratory system and their functions. Ask students to identify and describe each part to assess their understanding.


How is most energy produced?

Most energy is produced by the breaking and reforming of molecular bonds. A car's combustion reaction in which fuel is converted into energy, co2 and water is a good example of this. Energy is rarely produced on the atomic level, such as a nuclear power plant or an atom bomb. Energy is produced this way through Einstein's E=mc^2. In an atomic reaction the mass of the products is slightly less then the mass of the reactants. Plug the change in mass into Einstein's equation and you get a lot of energy. To recap, most energy is made on the molecular level with endothermic (reactions which absorb energy) and exothermic reactions (reactions which emit energy), however a small amount takes place on the atomic level.
