Honors Biology Chapter 4 Study Guide 1. Describe the structure of the organelles described in chapter 4. ex)nucleus has a double membrane and nuclear pores. very basic 2. If a cell has an extensive Golgi apparatus what function/process would you expect that cell to do? stores proteins and alot of exporting (sending stuff out of the cell) 3.
Unit 7 P1 P1 TASK ONE Anatomy and physiology of a cell Name of parts of a cell | Anatomy(structures) | Physiology (function) | Nucleus | The nuclear envelope is a double membrane. Is has 4 phospholipid layers. It is also has large pores through which materials pass back and forth. | The nucleus regulates all cell activity. It does this by controlling the enzymes present.
Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating (.
Information will always start with DNA then it will travel to the RNA and then the protein. This information flow will also be followed through the cell as it travels from the DNA in the nucleus, and the Cytoplasm, then to the Ribosomes and the Endoplasmic Reticulum, and finally to the Golgi
BIO 5 June 12 essay 10a The importance of shapes fitting together in cells and organisms Plan- • Enzymes - lock and key model, induced fit, specific complementary shapes, digestion of lactose, restriction enzyme in DNA • RuBP binding with CO2 in light dependent reaction of photosynthesis • Muscles - contraction, sliding filament theory • Blood and oxygen - inhibitors blood glucose receptors on cell surface membrane Essay- There are numerous examples of of the importance of shapes fitting together in cells and organisms. For example ; within enzymes, DNA, photosynthesis, muscle contraction, and receptors. Enzymes are used in every aspect of biology to catalysts a reaction. As they bind to substrate molecules which have a specific complementary shape to the enzyme, to form enzyme-substrate complexes and finally the enzyme and the product. There are many models of enzymes, such as the lock and key model, which explores the structure of the enzyme and its ability to bind with a substrate molecule which is specific and complementary.
The importance of hydrogen bonding in biology Hydrogen bonds are extremely important in biological systems. Their presence explains many of the properties of water. They are used to stabilize and determine the structure of large macromolecules like proteins and nucleic acids. They are involved in the mechanism of enzyme catalysis. Properties of Water Property | Importance | Examples | Solvent | Metabolic processes in all organisms rely on chemicals being able to react together in solution.
Nucleus | The nucleus is the "Control Center" of the cell, which contains DNA (genetic information) in the form of genes, and also information for the formation of proteins.Information is carried on chromosomes, which are a form of DNA. | cytoplasm | The nucleus is the "Control Center" of the cell, which contains DNA (genetic information) in the form of genes, and also information for the formation of proteins.Information is carried on chromosomes, which are a form of DNA. | Golgi aparatus | The golgi apparatus of a cell is usually connected to an endoplasmic reticulum (ER) because it stores and then transports the proteins produced in the ER. | Mitochondria | "Mitochondria" is a plural term; which is appropriate as these are not found
From the text, I gathered that Ridley wrote The Agile Gene from a biological perspective of psychology. Ridley talks much about how genes affect people, their minds, and their bodies. And his very in-depth look at genes is what make me think he took a biological perspective. Ridley himself is not a psychologist. He is just a biologist, which explains his great knowledge of how genes work.
Evolution forces adaptations to changes in environmental conditions in a population. The diversity of life on earth reflects the wide variety of adaptations necessary and suggests that environmental conditions have varied widely over the life of the earth. 3. An ecological niche is a species’ way of life or its functional role in a community. Everything that affects its survival and reproduction (temperature tolerance, water needs, space needs, interactions with other organisms, etc.)
