1. What type of diet does a vegetarian follow? What different types of vegetarian diets are there‚ and what do individuals consume or not consume when following them? Vegetarian’s don’t eat‚ “meat (including fowl) or seafood or products that contain them”. The three types of vegetarians are‚ lacto-ovo‚ which are ” based on grains‚ vegetables‚ fruits‚ legumes‚ seeds‚ nuts‚ dairy and eggs”. Then there is lacto‚ “ which excludes eggs as well as meat‚ fish and fowl”. The last types is vegan‚ which

Protein biosynthesis is the process by which biological cells generate new proteins; it is balanced by the loss of cellular proteins via degradation or export. Translation‚ the assembly of proteins by ribosomes‚ is an essential part of the biosynthetic pathway‚ along with generation of messenger RNA (mRNA)‚ aminoacylation of transfer RNA (tRNA)‚ co-translational transport‚ and post-translational modification. Protein biosynthesis is strictly regulated at multiple steps‚ and error-checking mechanisms

INTRODUCTION The Gram Negative lab had two parts; the aim of the first part is to determine the concentration of gram negative bacteria in a water sample collected from a creek near Providence Road‚ Strickling. Gram negative bacteria have a cytoplasmic membrane‚ a thin peptidoglycan layer‚ and an additional outer membrane composed of phospholipids and lipopolysaccharides. Because gram negative bacteria have a relatively thin cell wall when compared to gram positive organisms‚ they are consequently

difference between a gram positive bacteria and gram negative bacteria is the differences in cell wall composition. Prokaryotes known as eubacteria have three basic forms: rods‚ cocci and spiral. The bacterial cell wall is the single most important contributor to cell shape. In addition to shape of cell wall‚ presence or absence of flagellum‚ and if present‚ positions of flagellum‚ the eubacteria can be classified according to Gram Stain. First and foremost‚ gram positive bacteria are

“Is a Vegan Diet Healthy?” In contemporary society‚ particularly in more progressive areas‚ choosing veganism as a lifestyle choice is becoming increasingly common. While the decision to apply a vegan philosophy to all aspects of one’s life (including clothing‚ personal care‚ and household items) generally stems from ethical considerations‚ the choice to adopt a vegan diet is often motivated by health concerns. A conscious vegan diet‚ free of processed foods‚ provides a plethora of vitamins‚ minerals

In our experiment‚ we will be testing three different proteins to see if they denature at the same temperature. A protein is a molecule containing amino acids created in ribosomes that have many functions‚ including being an enzyme and transporter‚ structuring‚ translating genetic information‚ and serving as a channel for charged molecules to pass through the cell membrane. As a molecule‚ a protein is shaped like a coil (Food Science Basics 2014). Denaturation is when a protein’s shape changes due

“Denaturation of Proteins” Denaturation is a process in which proteins or nucleic acids lose the tertiary structure and secondary structure which is present in their native state‚ by application of some external stress or compound such as a strong acid or base‚ a concentrated inorganic salt‚ an organic solvent (e.g.‚ alcohol or chloroform)‚ or heat. If proteins in a living cell are denatured‚ this results in disruption of cell activity and possibly cell death. Denatured proteins can exhibit
