The following article will add knowledge about “Cows can derive nutrients from cellulose because“. Let’s not forget to look at the content!
Cows can derive nutrients from cellulose because:
a. They produce enzymes that recognize the shape of the glucose-glucose bonds and hydrolyze them.
b. They re-chew their cud to break down cellulose fibers.
c. Their digestive tract contains microorganisms that can hydrolyze the bonds of cellulose.
d. They convert cellulose to starch and can digest starch.
Answer “Cows can derive nutrients from cellulose because”.
Metabolis refers to the many chemical reactions that occur within an organism. These pathways can either break down molecules to release energy or use energy to create more complex molecules.
Fermentation refers to the process where sugars are converted into alcohol and other products anaerobically by microbes such as bacteria. Many useful industrial products can be made by fermentation. Cellulose is also fermented by bacteria in cattle.
Cows have a digestive tract that is distinct from other animals. Cows have an extra chamber in their stomach that is the rumen. The bacteria lives in the rumen symbiotically.
The bacteria is useful in the digestion cellulose, which is abundant in leaves that cannot be digested by other organisms. The cow is a complete herbivore, so she must digest cellulose. The bacteria ferments it and produces many useful products. The bacteria can also be used to produce vitamin B12 in cows’ rumens.
The cow consumes chemical energy from the grass when it eats. This chemical energy is stored in the bonds between the atoms of the grass’ carbohydrates. The grass will be broken down once inside the cow to release the energy needed to make ATP. The ATP is then used to fuel cellular activity, releasing heat energy into our environment. After the energy is used to fuel cell work, the heat energy will be released into the environment.
So, cows an derive nutrients from cellulose because their digestive tract contains microorganisms that can hydrolyze the bonds of cellulose.
The last result is C – Their digestive tract contains microorganisms that can hydrolyze the bonds of cellulose.
Above is the solution of “Cows can derive nutrients from cellulose because“. If you have good solutions or comments, please leave a message.
