The mitochondrion is present in all other eukaryotes but functionally absent in the parabasilids and diplomonads.

In general, mitochondria are called powerhouses of the cell as they transform energy from one phase to another and also provide energy to the cells in the form of ATP.

Eukaryotic cells have high metabolic rates meaning their energy requirements are quite high which ultimately leads to the presence of a high number of mitochondria.

On the other hand, arabasalids and diplomonads are anaerobic with low metabolic rates and thus lack mitochondria.

Instead of mitochondria, these organisms have a special organelle called the hydrogenosome which regulates the activities of metabolism in them.

Which linkages would you expect to find at a branch point in glycogen or amylopectin?
shusha [124]

Answer:

α-1,6-glycosidic linkage.

Explanation:

The carbohydrates are the polymers made of the sugars and bonded together through the glycosisdic bonds. The monosaccharides are the simplest unit of the carbohydrates.

The glycogen and amylopectin share similar structural features. Both have α-1,4-glycosidic linkage in their linear structure. The branching has been introduced in the glycogen and amylopectin structure through the α-1,6-glycosidic linkage.

Thus, the answer is α-1,6-glycosidic linkage.

  • Many biotic and abiotic factors play a role in recycling nitrogen ( A )
  • Farming practices and chemicals lead to a build-up of nitrates in the soil ( E )

Nitrogen cycle is biochemical process whereby nitrogen is converted to various chemical forms as it passes through the atmosphere, Marine and terrestrial ecosystems .

Nitrogen cycle undergoes four ( 4 ) important processes which are :  

  • Fixation
  • Ammonification
  • Nitrification and
  • Denitrification

Hence we can conclude that The statements that describe steps taking place in the nitrogen cycle are :

Many biotic and abiotic factors play a role in recycling nitrogen and

Farming practices and chemicals lead to a build-up of nitrates in the soil
