Answer:
Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.
Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.
Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.
Answer: Chemoautotrophs like algae and plankten are able to use chemosynthesis for thier food.
So <u>maybe</u> it's autotrophs since they don't eat plant's or meat.
Answer:
Fermentation is a chemical reaction that takes place in the cytoplasm and occurs when oxygen is low or absent. Byproducts of fermentation may include lactic acid or ethanol. Fermentation yields less ATP than the electron transport chain.
Explanation:
Fermentation is a chemical reaction that occurs under anaerobic or low-oxygen condition whereby the NADH produced during glycolysis is oxidized to NAD⁺ with the production of lactic acid as well as other products such as ethanol.
Since oxygen is lacking, pyruvate and NADH produced in glycolysis cannot be oxidized. In order to produce energy in the form of ATP for the cells and tissues,the NAD⁺ is regenerated from NADH by the reduction of pyruvate to lactic acid by the enzyme lactate dehydrogenase. In some other organisms such as yeast and microorganisms, pyruvate is converted to ethanol and carbon dioxide.
The net production of ATP in fermentation process is 2 molecules of ATp much lesser than that produced in aerobic respiration.
It was affected by natural selection.
If this is wrong someone please tell me.
