Answer 1

Correct Question:

1. Why Anaerobic respiration is less efficient? (Aerobic respirations are always concluded to be more efficient.)
2. Why Neurons have branched dendrons?

Explanation:

1. When we compare Aerobic and Anaerobic respiration,

Anaerobic respiration is such respirations which happens in the absence of oxygen. While aerobic are the ones which need oxygen for respiration. In aerobic respiration, a single molecule of glucose produces 38 ATP molecules. In Anaerobic respiration, less number of ATPs are produced which proves that Anaerobic respirations are less efficient as compared to Aerobic respiration.

2. Dendrites are basically the extensions that receive signals and impulses released by cells of our body. There are receptors on entries that are designed to pick up the signals from other neurons. These signals result in electrical differences which are analyzed in the cell body. hence, these branched dendrites are important for this conveyance of information across.

Answer 2

Answer:

1. Anaerobic respiration is less efficient because breakdown of glucose is incomplete so the energy released this process is less as compared to aerobic respiration.

2. Neurons have branched dendrons to create new synapses and increase neural activity. Also the establishment of long term potentiation at dendritic spines change the sizes, shape and conduction.
