applications; polymers can do so much more. Polymers are the “recipe for life.” We find them everywhere we look. For example, turn to your friend. What is he or she made of? The answer is polymers. Polymers make up essential molecules in our bodies, such as proteins or nucleic acids. They may be microscopic, but their functions in our bodies are important. Background Information There is so much more to being “biological” than just being related to biology. Polymer Structure Biological…

material - DNA that makes up the genes and chromosome. The Ribosome: ~Made of dozens of different proteins as well as RNA, also found in large numbers in the cytoplasm of living cells. Ribosome are typically composed of two subunits: • Large subunit • Small subunit “ Free” Ribosome makes proteins that remain inside the cell, “Bound’’ Ribosome make proteins that are exported from the cell. ~Protein Synthesis ~Chemical reactions is molecules that are brought into contact with one another.…

Cell membrane- A cell membrane is a fine structure that can also be referred to as a plasma membrane. Both Eukaryotic and prokaryotic cells are enclosed by a cell membrane. The functions are to keep a steady shape of the cell and to control particles moving into and out of the cell. These particles may be ions or molecules. Cell wall- Prokaryotic cells have a cell wall whereas eukaryotic cells don’t. The cell wall is what provides shape and protects the cell components. Nucleus- Nucleus is only…

One receptor on the cell membrane binds to one type of hormone. The binding hormones change the shape of the receptor, which causes the response to the hormone. Through the process of steroid hormone action, the hormone goes through a certain process of two steps. The hormone binds to receptors on the nuclear membrane once it is inside the cell that produces an activated hormone-receptor complex that binds to DNA, activating genes that increase the protein production. The action of…

have essential functions like as source of energy, materials for building new body mass such as muscles, and other molecules with essential functions like hemoglobin, which carries oxygen in the blood. These biomolecules are carbohydrates, lipids, proteins and nuclei acids. Biomolecules are called polymers (large molecules) which are composed of smaller molecules known as monomers. 11.1 Elements Present in Biomolecules Biomolecules are organic compounds, thus they are composed primarily of…

mitochondria. This is the process of breaking down food in the presence of oxygen to form ATP. ATP stands for Adenosine Triphosphate which is an energy bearing molecule found in all living cells1. Things such as bacteria can perform this with their outer membranes. When a person runs, they use cellular respiration to create energy in the form of ATP which allows their muscles to move. Many other energy-consuming reactions of metabolism are done using the energy from ATP molecules1. There are two…

do. The nucleus includes chromatin (protein and DNA). It also contains Nucleolus (nucleoli is plural). These nucleoli are responsible for ribosome production. If the nucleus were to suddenly malfunction, this would mean that the cell would have no directions, and nothing to direct them, so all activity would completely stop. Cell Membrane: The cell membrane is the organelle in the cell which determines what can come in and out of the cell. The cell membrane itself is a double layer of…

the mitochondria? Where did this organelle come from and what does it do? The Mitochondria is the main source of energy or powerhouse in a cell. They are eukaryotic organelles that contain their own ribosomes and DNA and are surrounded by a double membrane. The more active a cell is, the more mitochondria are created. Depending on the structure and the shape of a cell, how much the mitochondria is constantly working to keep the cell functioning. Through cellular respiration this organelle…

to the ribosome. Lots of cells secrete proteins into their surrounding extracellular fluid. Some cells like hormones and neurotransmitters secrete regulatory molecules. Whereas others release digestive enzymes, antibodies, or mucus. Fibroblasts secrete collagen are the whole body and other structural proteins to deliver the body with strength and hold the body together. All proteins are synthesized at cellular structures called ribosomes. When the protein is used in the cell the ribosome stays…

is a synthetic core nanogel. On the outside it possesses a platelet membrane shell. The TRAIL is attached on the surface of membrane and Dox is loaded in the core of nanogel. ( Hu, 2015 para. 1) 2) Explain the mechanism of how the nanoparticle system delivers the drug to the cancer cell. Blood is taken from a patient. The platelets are collected from that blood. The isolated platelets are treated to extract the platelet membranes, which are then placed in a solution with a nanoscale gel…
