List and describe the three steps involved in aerobic cellular respiration in order. state what is made and used and how much atp is made at each step

The three steps of cellular respiration are 1 glycolysis 2 TCA cycle 3 Oxidative phosphorylation.

Explanation:

Glycolysis During glycolysis glucose is used and pyruvate is made.2 molecules of ATP is made in Glycolysis .

TCA  cycle During TCA cycle Acetyl CoA is used and oxaloacetate is formed.2 molecules of GTP is produced during TCA cycle.2 molecules of GTP is equivalent to 2 molecules of ATP.

Oxidative phosphorylation During this process NADH,FADH2 are used and water is formed.34 molecules of ATP is generated during oxidative phosphorylation.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
