1. Which of the following is NOT true for the cellular respiration process?
Question 25 answers T
A>he total amount of ATP that a cell gains for each glucose molecule that enters glycolysis depends on the presence of carbon dioxide.

B>Pyruvate produced during glycolysis enters a mitochondrion during the second stage of cellular respiration.
C>The final electron acceptor in aerobic respiration is oxygen.
D>Acetyl-CoA combines with a four-carbon molecule.
-------------------------------------------------------------------------
2. Why do plant cells contain both chloroplasts and mitochondria?

A>In the light, plants are photosynthetic autotrophs. In the dark, they are heterotrophs.
B>If plants cannot produce enough ATP to make sugars during photosynthesis, they can produce it during cellular respiration.
C>Sugars are produced in chloroplasts during photosynthesis. These sugars can be stored in the plant for later use during cellular respiration.

Apart from bad luck (i.e. lack of the appropriate mutations), is there a reason why photosynthesising organisms have not evolved the appropriate pigments for absorbing all the available sunlight reaching the Earth's surface? (This, of course, would make them appear black.) Is this a possible area for genetic manipulation, assuming we discover the required techniques - the creation of more photosynthetically efficient organisms?

Like for the formula Ca(H2PO4)2
The numbers are all below the letters..
How would you break that apart??
Like Calcium = 2?
Hydrogen = 2?
I'm confused.
