Bryan Yu Period 2 Biology Data Table Questions 1. It showed that fermentation started to occur once the oxygen is gone‚ and the yeast will respire anaerobically. It is proven once it smelled like alcohol. 2. Aerobic respiration occurs in the presence of oxygen‚ CO2 and water are produced‚ and occur in plant and animal cells. In Aerobic respiration‚ glucose is broken down into CO2‚ H20 and ATP; more ATP is released (38). Anaerobic respiration happens in the presence of no oxygen and occurs

Leaf anatomy‚ food for plants and animals‚ plant functions‚ and plant and animal cells are all subjects that were highly mentioned throughout the first quarter. The theme of Energy Transfer is prominent in all of these topics. The Interdependence in Nature is also a theme that comes up especially in plant functions‚ plant and animal cells‚ and leaf anatomy. Although there were many different sub-themes after many experiments‚ research‚ and discussion in class‚ I find that the two main themes that

Glycolysis Glucose cannot be used as directly by cell as a source of energy so cells use ATP as their immediate source of energy. * This conversion of glucose into ATP takes place during cellular respiration and there are 2 different forms of cellular respiration depending upon whether oxygen is available or not * Aerobic respiration requires oxygen and produces CO2‚ water and lots of ATP. * Aerobic has 4 stages: 1) Glycolysis – the splitting of the 6-carbon glucose molecule into

THE ROLE OF PROTEIN MISFOLDING AND AGGREGATION IN BSE When a protein misfolds it changes its behavior and function. If it becomes hydrophobic after once being polar. The properties and functionality of the protein are no longer useful to the organism and disaster results. PrPSc is hydrophobic‚ it avoids water inside of the cell…it attracts and attaches other proteins to misfolds and become hydrophobic …Misfolding spreads because the PrPSc act as chaperone proteins to convert PrPc TO PrPSc and

Chapter 1 - Scientific Methods Objectives 1. Demonstrate a basic knowledge of classroom/science safety. 2. Understand the purpose of a hypothesis‚ and identify when a hypothesis should be used. 3. Be able to identify the independent and dependent variables in a formalized hypothesis. 4. Differentiate between an observation and an inference. 5. Contrast quantitative and qualitative observations. 6. Given a data table‚ draw and label a graph. Including a title‚ labeled units‚ and legend. 7

A pump is a protein that hydrolyses ATP in order to transport a particular solute through a membrane in order to generate an electrochemical gradient to confer certain membrane potential characteristics on it. This gradient is of interest as an indicator of the state of the cell through parameters such as the Nernst potential. In terms of membrane transport the gradient is of interest as it contributes to increased system entropy in the co-transport of substances against their gradient. One of the

Cellular Respiration OVERALL EQUATION: C6H12O6(aq) + 6O2(g) -> 6CO2(g) + 6H2O(l) 3 OVERALL GOALS: 1. Break bonds between the 6-carbon molecules of glucose – results in 6 CO2 molecules 2. Move hydrogen atom electrons from glucose to O2‚ forms 6 H2O molecules 3. Trap as much free energy released as possible in the form of ATP Stage 1: Glycolysis Cytoplasm‚ 10 reactions‚ anaerobic Stage 2: Pyruvate Oxidation Mitochondrial matrix‚ 1 step process Stage 3: The Krebs Cycle Mitochondrial

Gabriela Rios-Martinez March 1‚ 2014 BIO 141 Exam 1 Study Questions Chapter 1: Biology and the Tree of Life (#1 – 4) 1. What is the difference between a hypothesis and a scientific Theory? Between a hypothesis and a prediction? What kinds of hypotheses are useful for scientific investigations that try to explain the natural world‚ and which are not? Give one or more examples of hypotheses that are and are not scientifically useful. (a.) A scientific theory has two components; a pattern

Introduction: During this unknown lab report various test were performed to differentiate microbes from each other and to compare metabolic and biochemical process. The gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan
