How does temperature affect the rate of respiration in germinating peas?

How does temperature affect the rate of respiration in germinating peas?

At higher temperatures, germinating peas respire faster than at lower temperatures. Cellular respiration depends on catalysts called enzymes which work more efficiently at an optimal temperature range. Also molecules generally move faster at higher temperatures, therefore allowing the reaction occur more quickly.

At which temperature did the peas respire the most?

The ideal temperature range for pea respiration to occur is between 10 degrees Celsius (50 degrees Fahrenheit) and 30 degrees Celsius (86 degrees Fahrenheit).

How do germinating peas respire?

All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. It is known that pea seeds undergo cell respiration during germination. Using the CO2 Gas Sensor, you will monitor the carbon dioxide produced by pea seeds during cell respiration.

Is cellular respiration occurring in germinating peas germinating peas boiled and Nongerminating peas?

The Effect of Boiling on the Rate of Aerobic Respiration of Germinating Peas. Aerobic respiration is an enzyme mediated process during which glucose is used to make ATP to fuel the cells energy needs. Unboiled germinating peas were found to have a more rapid rate of aerobic respiration than boiled non-germinating peas.

How does temperature affect the rate of respiration?

The increase in temperature enhances the rate of cellular respiration. It is due to the heat speeds up the reactions, means the kinetic energy is higher. It means reactions speed up and rate of cellular respiration increases. When temperature decreases, in order to conserve energy, cellular processes slow.

How does temperature affect anaerobic respiration?

Anaerobic respiration occurs in the absence of oxygen and is common in most prokaryotes like bacteria and archaea. A change in temperature affects the- rate of cellular respiration significantly. An increase in temperature results in the absorption of heat, thus making the reaction endothermic.

Why do germinating peas respire more?

Germinating peas grow rapidly. This growth process requires a lot of energy for cell division, so the rate of respiration in germinating peas is high. One way to measure the rate of respiration is to measure the heat produced in the process. Vacuum flask – to prevent heat loss from the container.

Does respiration rate increase with temperature?

Do peas use cellular respiration?

All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. Peas undergo cell respiration during germination.

Why do germinating peas respire faster?

Since the germinating peas are germinating or sprouting, they require a more extensive amount of energy or ATP. This allows them to have high oxygen consumption rates or respiration rates in this experiment.

Does cellular respiration occur in germinating peas?

Do germinating seeds go through cellular respiration?

To fulfill the high-energy needs of a germinating seedling, cellular respiration increases as a seed emerges from dormancy and begins germinating. As the seeds respire, they are taking in oxygen and respiring out carbon dioxide, but the carbon dioxide is absorbed by the calcium hydroxide.

What was the respiration rate of germinating peas?

The results showed that the germinating peas had the highest rate of respiration with a total loss of .32mL of O2 in 15 minutes, while the non-germinating peas had a lower respiration with a total loss of .19mL O2 in 15 minutes. The control group of beads did not respirate at all.

Which is faster the non germinating peas or the beads?

The non-germinating peas and the beads showed to consume barely any oxygen at all. In this lab, the germinating peas respiration rate proved to be faster than the respiration rate of non-germinating peas. Finally, this experiment showed that respiration rates increase as the temperature increases.

Why does cellular respiration occur in room temperature peas?

Higher temperatures tend to promote energy and metabolic excitement. Based on the results of the experiment, it is safe to conclude that Cellular respiration is occurring in germinating and non-germination peas, however it occurs much faster in the highly active, room temperature, germinating peas.

What was the water temp in the peas experiment?

In one of the baths, the water temperature was adjusted, by adding ice, to approximately 10 C, while the other was allowed to settle at room temperature (about 25 C). After a 50 mL graduated cylinder was filled halfway (to 25 mL) with water, 25 germinating peas were placed in the graduated cylinder.
