What would happen to life on earth if the rates of photosynthesis and cellular respiration in all phototrophs were equal?

2 answers:

Plants hold extra sugar to get them through the night. If all rates were equal they would not have the excess sugar to help them survive the cold weather. This however is a far reaching question and would not happen, making my answer hypothetical.

Answer:

When the level of release of carbon dioxide during respiration and use of carbon dioxide during photosynthesis this results in a compensation point. At compensation point the net available carbon dioxide to phototrophs becomes zero. As, carbon dioxide is the chief ingredient for photosynthetic products like glucose and oxygen. These products are used up during the process of respiration. When the rates of two processes photosynthesis and respiration becomes equal. Phototrophic organisms will not be able to compensate for lack of carbon dioxide levels. Phototrophs will not be able to produce their food in the form of glucose and hence will not be able to respire too. This will result in lack of overall available food from phototrophs and lack of available oxygen for respiration. This will result in decline of organisms on earth.

Which statement BEST describes the relationship between adenosine diphosphate (ADP) and adenosine triphosphate (ATP)? A. With an

Shalnov [3]

Answer:

The correct answer would be C. With an input of energy, ADP combines with a phosphate group to become ATP.

Inorganic phosphorus and energy are added to adenosine diphosphate (ADP) in order to convert it to adenosine triphosphate (ATP).

This reaction is usually catalyze by the enzyme ATP synthase. It present in inner membrane of mitochondria of the cell as well as in the thyllakoid membrane in chloroplast.

ATP synthase uses the energy provided by chemiosmosis i.e. flow of protons down the gradient across the membrane through this enzyme. Proton gradient is formed either by photosynthesis or by cellular respiration.

ADP + inorganic phosphate (Pi) + energy → ATP + H₂O

ATP is used as the energy currency of the cell which breaks down to release inorganic phosphate group and energy which is used in various metabolic processes.

When testing the temperature of catalase, why did the enzyme catalase work best at 37°C? (Select all that apply.)

mojhsa [17]

Answer:

The correct answers are: B) Catalase works best at human body temperature, C) Normal human body temperature is 98.6°F, which equals 37°C.

Explanation:

Catalase is an enzyme found in our bodies that has the important task of breaking down hydrogen peroxide, a molecule that is very toxic. For catalase to work at its optimus speed, it need the body to have a temperature of 37° celsius -98.6°F-, which is what we normally call human body temperature. If the temperature rises or falls below body temperature, catalase will still work but at a much slower rate, until it stops working completely.

Not all enzymes work best at human body temperature, some enzymes reach their optimus state at higher or lower temperatures; but it is important to remember that enzymes are proteins, and proteins denaturalize when the temperature becomes to high, making them lose their shape and function.

Describe the steps in making packaging and exporting a protein from a cell

irina [24]

Answer:

The steps in making packaging and exporting a protein from a cell are listed below in the following points:

Protein is made from the Ribosomes.

These proteins are gathered in the endoplasmic reticulum.

From ER the proteins are exported to the Golgi bodies. These Golgi apparatus is found in the vesicles.

The Golgi bodies modify the protein to suitable forms that can be absorbed.

Finally it is transported to all part of cells in our body.
