Biology
1 answer:
Vesna [10]3 years ago
4 0

Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.

Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify

How many total ATP are created with Cellular Respiration? What are the processes in which ATP is generated and how many ATP are
Setler79 [48]

Answer:

Explanation:

There is a total of 38 ATP produced. ATP is produced from 3 different steps. The first step is Glycolysis which produces 2 net ATP. Next, is the KREBS cycle (aka the Citric acid cycle) which also produces 2 ATP. The final step is the Electron Transport Chain, which produces 34 ATP.

Anabolic reactions require an input of energy, while catabolic reactions release energy. When talking about the metabolism, ATP is released through catabolic reactions. To grow and build muscles, for example, anabolic reactions are need (because you need food to gain muscle mass).

Anaerobic respiration means that NO OXYGEN is present while aerobic respiration takes place in the presence of oxygen. It is important to note that ONLY GLYCOLYSIS can occur during anaerobic respiration. Also, fermentation occurs during anaerobic respiration. There are two types of fermentation; lactic acid and "alcoholic". basically, lactic acid fermentation produces, well, lactic acid (which is used in yogurt and it's also the cramps you feel while running the mile in gym). Alcoholic fermentation is what is used to make alcohols like isopropanol or drinking alcohols like vodka.

Hope this helps :)
