INTRODUCTION: All cells need to have a constant energy supply. The two processes by which this energy is attained from photosynthetic materials to form ATP are cellular respiration and fermentation. (Hyde‚2012). Fermentation is a way of harvesting chemical energy that does not require oxygen. (Reece et al. 2012). When the body is deprived of oxygen it will then begin to meet its energy needs through the slow process of fermentation. In our lab we investigated alcoholic fermentation by using yeast‚ which

a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution. Comparison chart All attributes Differences Similarities | Eukaryotic Cell | Prokaryotic Cell | Nucleus: | Present | Absent | Number of chromosomes: | More than one | One--but not true chromosome: Plasmids | Cell Type: | Multicellular

Compare/Contrast Maya Angelou’s “Champion of the World” and Amy Tan’s “Fish Cheeks” both capture the authors’ past experiences of oppression‚ and convey their struggles with identity. Both authors are from minority cultures‚ and both describe the same harsh pressures from the dominant culture. Both author’s share situations of being outcasts‚ coming from different racial backgrounds and trying to triumph over these obstacles. Tan and Angelou speak about the differences between their childhood

organisms catabolize organic molecules within their cells and use the energy released to manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve oxidation of foodstuffs‚ yet only the latter requires oxygen. Cellular respiration is a very complex process that consists of many steps that take place inside the cell‚ in an organelle called a mitochondrion. Mitochondria

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

“caricatured” as anti-gay. The Huffington Post’s Paul Raushenbush quickly wrote up a response‚ saying that “The hard reality that Cardinal Dolan and all Christians need to face up to is that the Catholic Church along with every other church whether Orthodox‚ Protestant or Catholic has been horrifically‚ persistently and vehemently anti-gay for almost all of its history.” Then Raushenbush hauled out a familiar argument: “Let’s just be very clear here —if you are against marriage equality you are anti-gay

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

The debate that girls and boys should be playing on the same team has gone on for quite a while. Boys think girls cant do most of their physical activities. On the other side girls think boys cant do most of their physical activities. This debate has gone on for such a long time‚ now it is just silly. Each side has their own opinions‚ but they can never agree with each other. I think girls and boys should be able to play on the same team‚ but we should give them that decision if they want to or not

In bio lab‚ my lab partners and I did a lab experiment involving yeast fermentation. Fermentation is an anaerobic process to regenerate NAD+ to keep glycolysis active. Yeast preforms ethanol fermentation which create ethanol and NAD+. The class used six different types of sugars to determine which fuels fermentation by measuring the amount the carbon dioxide bubbles produced by the yeast. Yeast are single-cell fungi that cannot make their own food. They take the sugars in the surrounding environment
