What is the purpose of the glass beads in the cellular respiration lab?
The purpose of the beads is to ensure that each respirometer is uniform in volume. The vial with glass beads alone will permit detection of any changes in volume due to atmospheric pressure changes or temperature changes.
Why germinating seeds would be using cellular respiration at a much higher rate than Nongerminating seeds?
It requires a lot of energy to break the seed coat and as it continues to grow this energy need increases. Respiration is required to access this energy so as the seed germinates its respiration rates increase. Non-germinating seeds, however, are dormant and use very little respiration.
How will you determine the rate of cellular respiration?
There are three ways to measure the rate of cellular respiration. These three ways are by measuring the consumption of oxygen gas, by measuring the production of carbon dioxide, or by measuring the release of energy during cellular respiration. In order to measure the gases, the general gas law must be understood.
What would you expect to happen to the respiratory rate if the peas were submerged in a cold water bath instead of a room temperature bath Why?
The rate of cellular respiration will be higher in germinating peas in cold and room temperature water baths than in that of the beads or non-germinating peas. The cooler temperature in the cold water baths should slow the process of cellular respiration in the peas.
What is the actual goal of cells that going through cellular respiration?
Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.
What are the two types of cellular respiration?
There are two main types of cellular respiration—aerobic respiration and anaerobic respiration. Aerobic respiration is a specific type of cellular respiration, in which oxygen (O2) is required to create ATP.
Do dry seeds consume oxygen?
Seeds need oxygen so that they can produce energy for germination and growth. The embryo gets energy by breaking down its food stores. Like all organisms, this is done through a process known as aerobic respiration. —a series of reactions where energy is released from glucose, using oxygen.
Why is cellular respiration important for germinating seeds?
Germinating seeds carry out cellular respiration processes in much the same way as plant and animal cells do. … The ATP molecules produced by cellular respiration provide the energy for seed germination to begin and fuels the cell-building activities that ultimately form the plant body.
Why do germinating seeds go through cellular respiration while plants do not?
It is necessary for germinating seeds to undergo cellular respiration in order to acquire the energy they need for growth and development. Unlike their mature relatives, seeds do not yet have the necessary photosynthetic abilities needed to produce their own energy sources.
How will cellular respiration affect oxygen levels?
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Which is the main function of the process of cellular respiration?
The main function of cellular respiration is to synthesize biochemical energy. Cellular respiration is essential to both eukaryotic and prokaryotic cells because this biochemical energy is produced to fuel many metabolic processes, such as biosynthesis, locomotion, and transportation of molecules across membranes.
