Answer:
The <u>Kerb’s/ Citric Acid/tricarboxylic acid (TCA) Cycle</u> of aerobic respiration produces FADH and NADH and releases CO2
Explanation:
The Kerb’s Cycle is termed as the cell’s biochemical hub because its main function is to harvest high-energy electrons from carbon fuels. 
It is constituted by a series of eight steps of chemical and enzymatic reactions including redox, condensation, hydration, dehydration, decarboxylation etc. 
One complete Kerb’s Cycle produces 2 carbon dioxide, 1 GTP, 3 NADH, and 1FADH2 molecules. Each glucose molecule yields two acetyl-CoA molecules and hence each glucose molecule requires two Kerb’s cycle.

Answer: d)All of the above
Explanation: Competitive effect is defined as the interaction created between species or organism , which usually results in negative situation. There are certain condition for the competition such as  supply of any resource in limited quantity, etc.So competition is also invoked by the density of the species present and in order to exist  in an ecosystem and thus there is the high chances of the overlapping of species as well.
Therefore,option(d) is the correct option.
