1. A clementine in my fridge is covered with a nice blue-green lawn of mold, a common decomposer. Assuming that the clementine did not dry out, what do you predict is the weight of the clemintine and mold together compared to the starting weight of the clementine and WHY?
2. You eat a strawberry high in glucose content. How could a glucose molecule from the strawberry provide energy to move your little finger?
A)The glucose is digested into simple molecules having more energy.
B)The glucose reacts to become ATP (Adenosine Triphosphate).
C)The glucose is converted into energy.
D)The energy of the glucose is transferred to other molecules.
E)The energy of the glucose is transferred to CO2.and H2O.
EXPLAIN WHY
1. To predict the weight of the clementine and mold together compared to the starting weight of the clementine, we can consider the process of decomposition by mold.
Mold is a decomposer, which means it breaks down organic matter like fruits and vegetables. During the decomposition process, mold obtains its energy and nutrients by feeding on the organic material, in this case, the clementine. As it consumes the clementine, the mold will grow and multiply, increasing its own mass.
However, some of the mass of the clementine may be lost as the mold breaks it down. This can occur through the release of gases, such as carbon dioxide, as well as the breakdown of organic molecules into smaller components that are absorbed by the mold.
Therefore, in general, we would expect the weight of the clementine and mold together to be slightly less than the starting weight of the clementine due to the loss of mass during decomposition.
2. In order to understand how a glucose molecule from a strawberry can provide energy to move your little finger, we need to look at the cellular process of energy production.
Glucose is a type of carbohydrate and acts as a fuel source for cellular respiration. When you eat a glucose molecule from a strawberry, it enters your digestive system, where it is broken down into simpler molecules through the process of digestion.
Once broken down, the glucose molecules can be transported to cells throughout your body, including the muscles in your finger. Inside the cells, glucose undergoes a series of reactions called cellular respiration. In one of these reactions, glucose reacts with oxygen to produce adenosine triphosphate (ATP). ATP is a molecule that provides energy to the cells.
Therefore, the correct answer to how a glucose molecule from a strawberry can provide energy to move your little finger is B) The glucose reacts to become ATP (Adenosine Triphosphate). Through the process of cellular respiration, the energy contained in the glucose molecule is converted into ATP, which is then used by the cells for various functions, including muscle contraction and movement.
