This video discusses the basics of cell biology, including the cell structure, life cycle, metabolism, and function. It also covers the importance of biochemistry in the cell, and how deficiencies in certain vitamins and minerals can lead to health problems.

00:20:00 In this video, the professor Amelia Bayern introduces the topic of biochemistry and the cell. She starts by talking about the cell and its structure. She also covers the cell's life cycle, its metabolism, and how it functions. The professor then takes questions from the students and goes over the next topic, the cell membrane.
00:25:00 This video discusses the basics of cell biology, starting with the cell and its structure. It goes on to discuss different types of cells and their important role in the body. Finally, it talks about the theory of cellularity, which is when cells become different, multi-cellular organisms.
00:30:00 The video discusses the idea that all organisms are composed of a single cell, and that all cellular functions are integrated within this one unit. It also discusses the work of Robert Brown, Rudolf Virchow, and Leonardo da Vinci, who all contributed to the development of this theory. The video finishes with a discussion of the cell as a biological unit, and how it is responsible for everything from basic cellular functions to the development of organs and tissues.
00:35:00 Cells are made up of proteins and cells need energy in order to function. Carbohydrates are the main source of energy for cells and are found in all types of cells including prokaryotic and eukaryotic cells. There are five main types of biomolecules in cells: carbohydrates, lipids, proteins, nucleic acids, and vitamins. Carbohydrates are important for the cell to function, and when the cell's diet includes carbohydrates, the carbohydrates provide energy for the cell.
00:40:00 This video covers the basics of cells and cellular metabolism. The main points discussed are the disaccharides, monosaccharides, and polysaccharides. There is also discussion of carbohydrates, proteins, and lipids. The second half of the video focuses on how these substances are used by the body in different ways.
00:45:00 This video discusses the cell and its metabolism. It explains that cells can be composed of either glucose or protein, and that proteins are made of amino acids. The two main classifications of proteins are fibrous and globular. Fibrous proteins are divided into two types, lineal and globular, and are composed of amino acids in a linear or spherical arrangement. Globular proteins are composed of amino acids in an ovoid or egg-shaped arrangement. The cell's genetic material is made up of proteins, which are essential for the formation of tissues and organs.
00:50:00 This video discusses the roles of cells and their metabolism. The basic building blocks of cells are nucleotides and other molecules of carbon. The carbon barandal is the phosphate with the sugar that is a ventosa. These are heavy molecules. Proteins are also made of heavy molecules. There are general classifications of proteins, and I tell you that proteins are also used to form structures to form the same cell membrane and organs. An example is collagen, which is a structural protein found in skin, tendons, and joint tissues. Enzymes are proteins, and we have hormones that are substances emitted by glands that are transported to another organ to activate or delay it. Vitamins are also divided into two categories, liposoluble and hydrosoluble. Vitamins A, K, E, and D are all liposoluble vitamins. Vitamin C is a hydrosoluble vitamin. As you can see, vitamins are important for the health of cells and are necessary for the formation of hormones. We also have proteins that are responsible for clotting. For example, we have serum protein, which is a type of clotting factor. We also have reserve proteins, like eggs. The white part of eggs is the albumin, and this
00:55:00 This video discusses the importance of cells and the cellular metabolism. It discusses how deficiencies in certain vitamins can lead to various health problems, including vision problems. The video also discusses the importance of dietary sources of biochemistry, including vitamins, minerals, and plant-based proteins.

In this video, the professor Amelia covers the basics of cellular biology. She starts with a discussion of the cell's structure and then moves on to discuss the different types of cells and their roles in the body. The video also covers the cell's genetic makeup and how it affects its ability to function. Finally, the video discusses the importance of the organelles in the cell and how they help the cell to function properly.

01:00:00 In this video, the professor Amelia will be covering the basics of cellular biology. Please stay for the second part of the session.
01:10:00 This video is about cell biology, with a professor discussing the different aspects of the topic. This video is free to watch, and is part of a series of ten lectures covering different subject areas for the university entrance exams.
01:15:00 This video covers the basics of cellular biology, including the cell's structure, its constituents, and how it functions. The video also covers the different types of cells and their roles in the body. Finally, the video discusses the cell's genetic makeup and how it affects its ability to function.
01:20:00 This video covers the basics of cell biology, from the small DNA strands that make up a cell to the organelles that carry out the cell's essential tasks. One important organelle is the ribosome, which produces proteins. Cells also have water-storage vacuoles, which are important in keeping cells hydrated. Finally, the video discusses eucariotic cells, which are highly evolved and have specialized organelles not found in prokaryotes.
01:25:00 This video explains the difference between a cell and a tissue, as well as the role of the cell's membrane in its function. It also highlights the importance of the cell's vacuole in digestion and excretion.
01:30:00 This video discusses the importance of the organelles called the Golgi apparatus, which helps cells process nutrients. The Golgi apparatus is also responsible for distributing proteins and carbohydrates throughout the cell. It is similar to the ribosomes, which are responsible for protein synthesis. However, the center of the Golgi apparatus is unique in that it contains centrosomes, which direct the chromosomes during cell reproduction.
01:35:00 This video discusses the cell, focusing on its nucleus. The cell is surrounded by a porous membrane because material needed for protein synthesis, such as ribosomes, needs to be inserted into the nucleus. The material in the endoplasmic reticulum must be injected into the nucleus, which is also porous. All of the chromosomes are found in the nucleus, which is a small, but important, organelle. The nucleus is made up of pure Rn, and also contains RNA-containing organelles, called ribosomes. When a cell needs to divide, new DNA must be formed. This process is aided by proteins called enzymes, which are located in the ribosomes. Finally, the video discusses differences between cells from different organisms, focusing on plants and animals.
01:40:00 The video discusses the difference between cellular and animal cells, and how cells in animals have different organelles, including vacuoles that digest food. It also discusses the cell wall and how it differs between cells. Finally, the video discusses the difference between plant and animal cells in terms of their cloroplast and pigment cells.
01:45:00 Cellular structure is shown, with both the cell's skeleton and its nucleus. Proteins are strung along these structures, and reactions in cells take place in the citoplasm. The cell membrane separates the cytoplasm from the nucleus. Cells can be classified according to their organelles, their genetic material, and their cell membrane. Vegetables differ in many ways from animals, including in their cell membrane and in the number and function of their lysosomes. This lecture summarized important differences between cells in plants and animals, and provided information on the free course offered to university students interested in biochemistry.
01:50:00 This video is a lecture on cellular biology, with the focus on the cell and its metabolism. The instructor discusses the topics that will be covered on exams, and provides tips on studying for them. She also provides a live demonstration of some of the concepts covered in the lecture.
