If a large molecule needs to move against the concentration gradient, what structure will need to be used ?
zubka84 [21]

Answer:

The structure of ATP will need to be used.

Explanation:

Adenosine triphosphate or ATP is an energy rich compound which undergo hydrolysis in presence of water to generate free energy.

         When a molecule is moving against its concentration gradient it requires the input of energy which is generally supplied by the hydrolysis of ATP molecules.

For example Na+K+ATPase uses the energy derived from ATP hydrolysis to transport Na+ inside the cell and K+ outside the cell.

Answer and Explanation:

The pectorals major is an enormous, fan-formed muscle covering the chest. It is included clavicular and sternocostal areas. Adducts and turns the upper arm. Transverse adduction and flexion of the pectoralis major is smooth movement. You can see the muscles extending far and contracting back effectively.  

The biceps brachii is a two-headed muscle. Despite the fact that most of the bulk is found anteriorly to the humerus, it has no connection deep down itself.

Lipase is an enzyme that breaks down fats
Amanda [17]

Answer:

3a. As we know and also mention in the question that lipase is an enzyme that digested and break down the fats into fatty acid and it is also known that the action of an enzyme is as follows:

Enzyme + substrate <===> Enzyme-Substrate <====> Enzyme + Product

and here, E+S <----> ES<---->E+P

So, E is Lipase  as the enzyme, S is fats,  and P is fatty acids

3b. The control group is in this experiment or research is the group in which activity of the lipase is tested with the help of the chemical Orlistat, present in the diet pill as the control group is used to compare the or test the results of the independent variable's response.

3c. The scientist's prediction would be that in the control group fats will not be digested by the lipase into fatty acids and will not lead to any side effects.

EleoNora [17]

Answer:

<h3>White sugar is polished and refined sugar. It has a high glyciemic index (Glycemic index)</h3><h3>GI represents the total rise in your blood sugar level following consumption of the food. White sugar probably has a GI of around 96 which is pretty close to the highest (100 of pure glucose). </h3>

<h3>Hence it is unhealthy because the body is unable to burn off this sudden spike in glucose levels.</h3>
