Biologists sometimes divide living organisms into two groups: autotrophs and heterotrophs. these two groups differ in ________.
Alina [70]
Their source of carbon. Autotrophs obtain their carbon from inorganic sources such as from atmospheric carbon dioxide. Examples of autotrophs include plants, and euglena ( a protist).
Heterotrophs on the other hand, obtain their carbon from organic sources such as other organisms. Examples of heterotrophs include all secondary consumers, and decomposers.

Which of the following chemical reactions proves the fact that the products of photosynthesis are reactants of respiration?
AlladinOne [14]
<span>The answer is:
Photosynthesis: 6 CO</span>₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Respiration: C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP<span>

Cellular respiration and photosynthesis are complement reactions to each other. These are reverse reactions. In cellular respiration glucose (</span>C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and oxygen (<span>O₂)</span><span>. </span>

24. What is/are the major potential energy product(s) formed in the Krebs Cycle (not the same as end-products formed a the end o
dexar [7]

Answer: a. NADH/FADH2

Explanation:

Complete oxidative degradation of glucose can be compartmentalized into four main biochemical steps: glycolysis, the formation of acetyl-CoA, the Krebs (citric acid or tricarboxylic acid cycle) and the electron transport chain where oxidative phosphorylation is performed. During respiration, an organic compound (usually sugar) is completely oxidized to form CO2 and H20. The Krebs cycle is the set of reactions leading to complete oxidation of glucose. It occurs in the mitochondria of eukaryotes and the cytoplasm of prokaryotes. Per each degraded glucose molecule, resulting in the final of the Krebs cycle:

• 6 molecules of NADH.

• 2 molecules of FADH2

• 2 molecules of ATP

• 4 molecules of CO2

Which gives our answer What is/are the major potential energy product(s) formed in the Krebs Cycle? a. NADH/FADH2 because 8 molecules of them in total are made.
