AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

produce a gas when sugar is available. For the third hypothesis‚ we did not expect yeast to produce a gas when no sugar or other food is available. The reason is that carbon dioxide is a product of respiration and is formed when the yeast respires. Therefore‚ when no food and sugar is available‚ respiration cannot take place. Hence‚ no carbon dioxide is formed.

Photosynthesis and Respiration Unit2 – IP 1. A) Photosynthesis space is a process in which the energy from light is used to produce carbohydrates. Aside from using light energy‚ photosynthesis includes carbon the oxide and water. A1) In order to generate energy aerobic respiration requires oxygen‚ although fats and proteins and carbohydrates can be consumed and processed as reactant‚ is the usual method of breaking down in glycolysis and usually requires the pyruvate to enter the mitochondrion

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 are responsible for converting digested nutrients into the energy-yielding molecule adenosine triphosphate (ATP) to fuel the cell’s activities. This function‚ known as aerobic respiration‚ is the reason mitochondria

Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all

are three main stages of cellular respiration are glycolysis‚ the citric acid cycle‚ and electron transport/oxidative phosphorylation. Enzymes play a role in cellular respiration. Enzymes are proteins that catalyze or affect the rate of chemical reactions. The main purpose of enzymes in cellular respiration is to help in transporting electrons from one molecule to another. These transfers are called redox reactions. Where the loss of electrons from one molecule oxidation must correspond with more

To understand that the lungs do not contain muscle and that respirations are therefore caused by external forces. To explore the effect of changing airway resistance on breathing. To study the effect of surfactant on lung function. To examine the factors that cause lung collapse. To understand the effects of

ANATOMY AND PHYSIOLOGY AN INTRODUCTION TO RESPIRATION In this essay we will consider a few major aspects of respiration. We shall first consider the interesting history of the study of respiration before moving on to our modern understanding of respiration. We will look at the structure and function of the respiratory system including the upper and lower respiratory tracts with a note on the control system. Secondly we will consider the physiology of respiration. Thirdly we will discuss some of the major

function. In photosynthesis and aerobic cellular respiration energy is being produced to cycle carbon between the functions. There is the function of maintaining life‚ helping aid chemical reactions‚ using the cell to help aid reation. All of these recycling processes help creates energy that is then in return used to aid their specific function. The life processes of nutrition and respiration are related to photosynthesis and Aerobic Cellular Respiration. All organisms use material from the outside
