After giving her dog a bath, a young girl suddenly died. The flea dip she was using on the dog contains a chemical called roteno

ne which inhibits the function of an enzyme that oxidizes NADH to NAD+. Her autopsy revealed massive cell death in her internal organs and damage to her mitochondria. The levels of NAD+ were very low and the levels of NADH were very high in her mitochondria. What part of cellular respiration was affected by the rotenone (1 pt)? How could this have led to her death (1 pt)?

In spite of the fact that this situation is probably not going to occur, rotenone is poisonous in light of the fact that it meddles with the electron transport chain (ETC) in mitochondria, so NADH would develop as recommended.

Ans.

The rotenone is toxic chemical, which targets electron transport chain of cellular respiration, during which NADH are oxidized to NAD+ provide energy for ATP synthesis. It inhibits electron transfer from complex I (iron-sulfur center) to ubiquinone.

The increased amount of NADH is increased in girl's cell as NADH does not get oxidized into NAD+, due to rotenone. As electron transport provides energy for ATP synthesis, inhibition of electron transport chain results in no ATP synthesis.

ATP molecules act as energy-providing molecules for all cellular activities. So, lack of ATP molecules results in death as cells lack energy to perform biological functions.

Thus, the part of girl's cellular respiration, affected by rotenone was electron transport chain and her death was caused due to inhibition of ATP synthesis.

Which of these products are made from a renewable resource?
aleksandr82 [10.1K]

Renewable resources are those which can be replaced naturally and repeatedly. For example, water, oxygen, and plants are examples of renewable resources.

Wood is a renewable resource as it is a part of trees. Trees are able to be replanted and can be cut down again, once they reach maturity. Plastics, glass, and steel are known as non-renewable resources as they cannot be replaced at a sufficient rate and usually have a limited supply. For example, plastics are created using a variety of different substances such as natural gas and oil (polyethylene). The Earth contains a limited supply of both substances, so plastic is deemed as being non-renewable.

As a result, the only renewable product in the choices provided above is a wooden spoon.

What is embedded in the phospholipid bilayer that helps in the movement of larger molecules ?
gladu [14]

Answer:

\boxed {\boxed {\sf A. \ Channel/Transport \  proteins}}

Explanation:

The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.

Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.

So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>

The interdependence of body systems is essential because
Zinaida [17]
The answer is letter C.
<span>
The interdependence of body systems is essential because all systems work together to maintain homeostasis. Homeostasis in body systems refers the regulation of internal conditions keeping it stable and relatively constant. In humans this refers to its ability to maintain stability in its internal environment while responding to changes in external conditions. It serves as a sensor that detects changes in the conditions that need to be regulated to meet the demands of the condition and give the necessary feedback. Regulation of body temperature and the balance between acidity and alkalinity are examples of homeostasis in the human body.</span>
