A Study of Cellular Respiration & Gas Production in Peas We conducted this lab in order to determine the relationship between gas production and the cellular respiration rate between germinating peas and dormant peas. Cellular respiration is the procedure of changing the chemical energy of organic molecules into a form of energy that can be used by cells called ATP (adenosine tri-phosphate). Cellular respiration is conducted in 3 processes: Glycolysis‚ Citric Acid Cycle‚ and Oxidative

mammals. 3) Slide 3: Why is the nucleus of the cell in slide 3 so large? In other words‚ what is this cell doing that requires that its nucleus be so large? (Please be specific). In eukaryotic cell in slide #3 has organelles including a nucleus containing DNA and mitochondria energy organelles .Compared to the prokaryotic cell which has the DNA in the cytoplasm smaller and simpler and doesn’t contain a nucleus or other organelles‚ it does have cell membrane. Bacteria and Archea are single celled

Cellular Respiration and Photosynthesis are two processes that occur in a cell. Cellular respiration coverts glucose and oxygen into ATP and its byproducts‚ carbon dioxide and water‚ are what cause photosynthesis to occur which is then converted into glucose and ATP and then release oxygen. Photosynthesis occurs in the chloroplast while cellular respiration occurs in the mitochondria. The glucose for cellular respiration is first split in the cytoplasm during the process glycolysis then the Kreb’s

Stem cells Nowadays‚ stem cells are the hottest topic in the medical field. More and more researches are performed to investigate these mystic cells. In order to go deeper into this topic and fully understand it‚ let’s first take a look at the stem cells themselves‚ their origins and characteristics which make them so unique and crucial for the medical field. Stem cells are very complex and complicated‚ and‚ that is why‚ it takes a lot amount of time to get to the bottom of their structure to be

1. INTRODUCTION A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight‚ while the term photovoltaic cell is used when the light source is unspecified.”Photovoltaics” the field of technology and research related to the application of solar cells in producing electricity for practical use.

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical
