The following options are attached to the question given above:
A) A eukaryotic cell that can make its own food
B) A prokaryotic cell that can make its own food
C) An aerobic bacterium
D) An anaerobic bacterium
ANSWER
The correct option is A.
Endosymbiotic theory is a theory that talks about the evolution of eukaryotic cells from prokaryotic organisms. The theory proposes that mitochondria and plastids {chloroplast}, which are found in eukaryotic cells were once prokaryotic cells. Based on this theory, an endosymbiosis of a cell with a cynaobacterium would result in a eukaryotic cell that can manufacture its own food because it contains plastids.
The best answer is starch.
Starch is a type of carbohydrate.
Carbohydrates are made of simple sugars, namely glucose. A simple sugar is a single molecule of a sugar. A single sugar molecule is called a monomer.
Starch is made of many monomers or units of glucose linked together and is thus called a polysaccharide. When it is broken down, the result is its many glucose units are separated from each other by breaking the chemical bonds that hold them together, and are thus released as simple sugars.
<u><em>NAD+ and H+ are not the same. </em></u>
NAD+ is an electron carrier. Reactions in metabolism oxidize food molecules and transfer those electrons (along with H+) to > NAD+ which is what forms NADH. Now, NADH is the reduced form of NAD+ and NAD+ is the oxidized form of NADH.
H+ on the other hand, is a proton. It is a hydrogen atom that lost it's electrons. So when you see NADH + H+, that means that the reaction removed 2 electrons and 2 H+ from the compound.
Without energy, nothing would exists. we wouldn’t even exist.
