Citric acid cycle

Explanation:

The results were -

Glucose: None

CO2: Increase

O2: None

ATP: Increase

NADH: Increase

  • We know that the Citric acid cycle is also known as the TCA cycle (tricarboxylic acid cycle) or the Krebs cycle. This cycle occurs in Mitochondria in case of eukaryotes. In this cycle acetyl-CoA is oxidized which comes from carbohydrates, proteins and fats and energy is released in the form of ATP.  
  • water is also used in this process. NAD+ gets reduced to NADPH. In this system carbon dioxide is produced as a waste byproduct. ATP is produced as the main product. ATP is also used as a source of energy.

How is the process of carbon fixation in CAM plants different from the process in C3 and C4 plants? a. CAM plants require a larg
Leya [2.2K]

Answer:

The correct answer would be option C.

Plants evolved different methods to prevent or reduce the effects of photorespiration.

The C3 plants are the most common plants which do not have any special methods or physiology to prevent photorespiration.

The C4 are the plants in which carbon fixation and the Calvin cycle takes place in different cells. Carbon is fixed in the mesophyll cells with the help of PEP carboxylase enzyme. It fixes carbon and converts PEP into oxaloacetate. The Calvin cycle takes place in the bundle-sheath cells.

In contrast, CAM (Crassulacean acid metabolism) plants are those in which carbon fixation and Calvin cycle are separated into time. The carbon is fixed during the night as it helps in reducing the loss of water through transpiration.

The Calvin cycle takes place during the day time in the same cell, that is, mesophyll cell.
