Answer:
Only about half the energy available in an organism is transferred to the consumer that eats it.
Explanation:
In an ecosystem energy flows in a linear fashion or in one direction. Energy from sun is fixed into chemical energy by green plants. The stored chemical energy from green plants is transferred to the herbivores then to carnivores who eat herbivores. During energy transfer, a part of energy is used for the growth and development of the organism and large amount of energy is released as heat into the environment and only 10 % of the energy stored in the organisms at each trophic level is transferred as a food for the next trophic level to support life. This is called ‘10 % law of energy transfer’.
The right answer for the question that is being asked and shown above is that: "A. Most enzyme-assisted reactions can take place at any temperature." The statement that is true about most enzyme-assistedreactions is that A. Most enzyme-assisted reactions can take place at any temperature.
The following given statements are true of trans-fatty acids:
A. Often created by treating plant oils with hydrogen
D. Occur naturally in in food
<u>Explanation:</u>
The unsaturated fatty acids that are produced by a method called hydrogenation through the addition of a hydrogen molecule to vegetable oils is understood as "Trans-fatty acids". According to the hydrogenation process the composition of the fatty acids varies. The unsaturated fatty acids trans structure receives one double conjugated bond and obtains a straight shape and rectifies the twisted shape created by cis bonds.
Increasing the concentrations of trans-fatty acids particularly in the red blood cell membranes can lead to blockage of the blood vessel as a whole and enhance the risk of heart disease. Meat and dairy products kind natural food materials include trans fatty acids.
<h2>Answer is option "E"</h2>
Explanation:
- Enzymes belong to the proteins category because enzymes are long chains of amino acids bound together by peptide bonds
- Enzymes have a special marker on them called an active site that, like a puzzle piece, fits with only one other type of molecule, generally referred to as a substrate. The substrate is a molecule that will undergo a reaction that results in it splitting into two separate molecules, called products
- The substrate-specific to a particular enzyme will bind at the active site, forming what is known as an enzyme/substrate complex. In other words, a complex formed by the union of the enzyme and substrate
- Hence, the right answer is option E "both A and B"
