The ultrasound features associated with the highest risk for cancer include a heterogeneous echotexture, calcifications, no hilus, a rounded appearance, cystic changes, and chaotic hypervascularity. These lymph nodes should always be biopsied even in the absence of a malignant-appearing thyroid nodule [13].
The reactants in the equation for cellular respiration are oxygen (O2) and glucose (C6H12O6).he main reactants of cellular respiration are: glucose(C6 H12 O6), water(6H2 O) and oxygen(6O2). The products of cellular respiration are: carbon dioxide (6C O2), water(12H2 â¦ O) and Energy (36 ATP).
The overall reaction for cellular respiration: (does this reaction look familiar? Overall, it is the reverse reaction of photosynthesis, but chemically, the steps involved are very different.) C6H12O6 + 6O2-----> 6CO2 + 6H2O + ~38 ATP . Whereas only photosynthetic cells can make sugar using photosynthesis, ALL cells need to be able to break down sugars they take in from their environment and turn it into energy to be used in cellular work....
