Macromolecules In Biology

My analogy from a cell is to a city. A cell has a cell membrane and in a city the city border acts as the cell membrane. The city wall in a cell acts like a cell wall. The cytoplasm can be a lawn in a city. Highways or road systems act like the endoplasmic reticulum in a city. The ribosomes in a cell organelle can be considered lumber or brick yard in a city. In a city post offices and UPS act as the golgi bodies. Solar energy plants are considered chloroplast. A city hall fence with a security guard can be considered as the nuclear membrane. Energy plants in cities can be considered the mitochondria. In cell organelles there is the nucleus and in a city the nucleus would

A cell is the basic unit of life, essential to maintaining the physiology of the larger organism. In animals, certain organelles metabolize food into energy, and then uses the energy for repair, growth and reproduction. Similarly, chloroplasts in plant cells transform sunlight into energy, a process known as photosynthesis.

44. The structure and properties of the phospholipids that result in the formation of a bilayer and the micelle are lipid molecules which origin a assemble automagically into the bilayers. Protection and concentration, Support, Selection and Catalysis are the eventual evolution of life on

Breaking down an organism leads scientists to identify cells. A group of cells create tissues, tissues combined are organs, and organs and their functions make up systems. Basically, cells make up living organisms. There are 2 kinds of cells: Prokaryotic and Eukaryotic. Within a prokaryotic, it doesn’t contain a DNA bounded nucleus; however, a eukaryotic cell does. Though the prokaryotic cell differs from a eukaryotic cell, they share a cell membrane. The cell membrane is composed of a phospholipid bilayer and proteins, which makes it selectively permeable. It is located outside of the cytoplasm and controls the movement of substances in and out of the cell. Its basic function is to protect the cell from its surroundings by selecting what can enter and exit the cell.

During the spring semester of my sophomore year, I had the opportunity to study in Singapore. My coursework included a wide selection of advanced-level biology classes that spanned the spectrum from anatomy to ecology. I was intrigued by the complexity that emerged at all levels of life. The way organelles work together to complete

Next, both the school and cells have a “mitochondria.” The mitochondria turns food energy into energy the cell can use. The generators, are similar to the mitochondria. The generator take gasoline and turns it into usable electricity.

Introduction: In this lab, we studied biomolecules. Biomolecules are molecules that are existent in all living organisms. The four biomolecules, we are learning in class are proteins, carbohydrates, lipids, and nucleic acid. The three biomolecules being addressed in the lab are proteins, carbohydrates, and lipids.

Macromolecules play a crucial role in the functions of living systems, and so it is important to be able to identify what substances might contain specific macromolecules. In this experiment, three tests were conducted on twelve sample solutions of different substances. The macromolecules being tested for were polysaccharides such as glycogen and starch, reducing sugars, and finally proteins. These three types of macromolecules were tested using the Iodine Test, Benedict’s Test, and Biuret Test respectively. The overall purpose of this experiment was to develop an understanding of why certain macromolecules might react with certain substances given their unique properties, as well as to identify an unknown substance based on the results of these tests.

Now that we understand the properties of life and the composition of cells, we can focus on the architecture or formation in terms of basic anatomy and physiology as our second area of exploration. The two types of cells (prokaryotic and eukaryotic) defined before have a few common things such as Plasma membrane (similar to animal cells); Cell wall (similar to plant cells); and Ribosomes, the

I am an education major and I want to own my own daycare one day. I am going to use a daycare to demonstrate the different organelles. Golgi apparatus is like the cook in a daycare. The cook and the Golgi apparatus both transfers proteins. Ribosomes are like food because ribosomes proved protein to that cell just like how food give humans protein. The Cytoplasm is like the building of the daycare. The Cytoplasm holds all of the objects in the cell, and the building holds everything in the daycare together. The Nucleus is like an office because, the nucleus hold all of the information just like an office. The Cell Membrane is like an outlet cover it stop the kids from putting their hands inside of the outlets It is away the teachers can know

The purpose of this lab was to discover which molecules are found in certain foods. I expected to learn more about the molecules that we tested for, which were simple sugar, starch, and protein. I also expected to learn more about macromolecules, since simple sugar and starch are both carbohydrates, and I expected to learn more about what makes up food. If each food is tested for simple sugar, starch, and protein, then milk will have simple sugars and protein, crackers will have simple sugars, bananas will have starch and simple sugars, and egg whiles will have protein.

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

Lysosomes: Lysosomes contain enzymes that break down and digest large molecules into smaller molecules. To me this sounds like the function of the stomach, which also digests large materials into smaller materials to send into the body as nutrients and proteins. The stomach and lysosomes also share an acidic environment for the material to be digested in.

In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.

Both contain a small amount of DNA and are semiautonomous. They will grow and reproduce within the cell. It is believed that mitochondria and plastids were
