How does temperature affect the rate of respiration?

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.

Why would germination have an effect on respiration rate of peas?

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.

Does the temperature of germinating seeds affect the rate of respiration do plant seeds consume more oxygen at higher temperatures than at lower temperatures?

Plant seeds do consume more oxygen at a higher temperature than lower temperature. When the plant seed is within a cooler surrounding, it will not consume as much oxygen because the rate of respiration will slow down so the enzymes will not need to work as fast.

How does temperature affect cellular respiration in the germinating pea seeds?

The rate of cellular respiration will slow down as temperature exceeds the optimal range. This is because enzymes and other cellular proteins will start to be “shaken apart” by the excessive energy associated with high temperatures.

How does temperature affect 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.

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

As oxygen is consumed to provide energy, germinating seeds release carbon dioxide. Additionally, that at higher temperatures, the rate of cellular respiration in the seeds will increase.

How does temperature affect the rate of cellular respiration in germinating white beans?

If respirometers with germinating mung bean seeds are placed in 0, 21, and 37 degrees Celsius, then the beans in the 37 degrees will undergo the most respiration because the rate is increased in warmer temperatures because the molecules are moving faster, therefore bumping into each other more often and making more ATP …

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.

How does temperature affect the rate of respiration of germinating seeds?

How does temperature affect the respiration of yeast?

The higher the temperature, the more carbon dioxide will be released by yeast, therefore forming a greater amount of bubbles. Once the temperature gets above a certain point the rate of respiration will decrease.

Why does temperature increase breathing rate?

Fever: As the body temperature increases with a fever, respiratory rate can also increase. The increase is the body’s way of trying to get rid of the heat.

Do germinating peas have higher rate of cellular respiration?

The rate of respiration in germinating peas was compared to the rate of the non-geminating peas. These peas were placed in two different temperatures: 10ºC and 23ºC. The hypothesis of this lab states that if the peas are germinated then the rate of cellular respiration will be higher in both room temperature and cold temperature.

What is the difference between germinated and non-germinated peas?

Germinated peas are the peas that have a lot of cellular respiration and consume a lot of oxygen. The non germinated peas consumed very little oxygen and so therefore had very little cellular respiration.

Do dry peas consume more oxygen than germinated peas?

Our data says that the dry peas consumed almost as much oxygen as the germinated peas did in the same water bath. The larger amount of oxygen consumption in the dry peas was not expected but can be explained by human error as well as the pressure and temperature changes that are stated and explained above.

Do peas and beads respire in cold temperatures?

This hypothesis was reasoned out with the assumption that cold temperature slows down cellular respiration and the non germinated peas and beads respirate very little if at all.
