A young dog has never had much energy. He is brought to a veterinarian for help and she decides to conduct several diagnostic te

sts. She discovers that the dog's mitochondria can use only fatty acids and amino acids for respiration, and his cells produce more lactate than normal. Of the following, which is the best explanation of the dog's condition? A young dog has never had much energy. He is brought to a veterinarian for help and she decides to conduct several diagnostic tests. She discovers that the dog's mitochondria can use only fatty acids and amino acids for respiration, and his cells produce more lactate than normal. Of the following, which is the best explanation of the dog's condition? His cells cannot move NADH from glycolysis into the mitochondria. His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane. His cells have a defective electron transport chain, so glucose goes to lactate instead of to acetyl CoA. His cells lack the enzyme in glycolysis that forms pyruvate.

Answer:

The correct answer would be His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane.

In cellular respiration, glycolysis takes place in the cytoplasm of the cell and converts glucose into 2 molecules of pyruvate. Pyruvate is then transported into the mitochondria for further oxidation.

It is transported into the mitochondria with the help of transport protein pyruvate translocase where it is decorboxylated to produce acetyl-CoA. This acetyl-CoA then enters the Krebs cycle to produce ATP (adenosine triphosphate) with the help of oxidative phosphorylation, electron transport chain and chemiosmosis.

In absence of this transport protein, the cell can not completely oxidize the glucose or carbohydrate. It switches to the metabolism of fats and amino acids in order to meet the energy demands of the cell.

Stella [2.4K]

Answer:

α-ketoacid; glutamate.

Explanation:

The amino acid synthesis is important for all the living organism. Different organism uses different strategy for the synthesis of amino acid.

The α-ketoacid is generally used in the synthesis of amino acid especially in microorganisms and plants. The transamination of glutamate results results in the formation of particular alpha-keto acid.

Thus, the correct answer is option (b).

This chart Presents data on greenhouse omissions caused by human activity from 1990 to 2012 which questions will help clarify th
Dahasolnce [82]

Answer:

None of the questions asked can be answered completely from the graph provided 

Reason

1) Which source of electricity generation caused the most emissions?: The graph does provide the information of greenhouse gas emission from different sectors like electricity, transport, industry, agriculture, commercial and residential.  Electricity can be generated from several sources like hydrothermal, nuclear, etc. However, information of how these sources contributes towards greenhouse gas emission via electricity sector is not provided in graph

2) What types of industries are responsible for greenhouse gas emissions?: The graph does provides the information about total greenhouse gas emissions from industries. However, individual contribution from different types of industries cannot be answered.

3) Which natural sources of greenhouse gas emissions are shown here?: The graph provides information about greenhouse gases emission only due to human activity like electricity generation, agriculture, etc. and not from natural sources. 

4) Why is agriculture the largest source of greenhouse gas emissions?: The reason for largest emission of greenhouse gas due to agriculture cannot be answer from information provided.

5) What caused the dip in greenhouse gas emissions in transportation after 2007?: The reason for dip in greenhouse gas in transportation cannot be answer from information provided.

Answer:

1. Carbohydrates - It serves several key functions in your body. They provide you with energy for daily tasks and are the primary fuel source for your brain's high energy demands. Fiber is a special type of carb that helps promote good digestive health and may lower your risk of heart disease and diabetes.

2. Protein- You use protein to make enzymes, hormones, and other body chemicals. Your body also uses protein to build and repair tissues. Protein is an important building block of bones, muscles, cartilage, skin, and blood.

3. Lipids - This is essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection

4. Nucleic acids are very important for cell functioning, and therefore for life. There are two types of nucleic acids, DNA and RNA. Together, they keep track of hereditary information in a cell so that the cell can maintain itself, grow, create offspring and perform any specialized functions it's meant to do.

Embryos are an evolutionary adaption of
lara [203]

El estudio comparado del desarrollo de los embriones aportaría, según el Darwinismo, otra de las pruebas clásicas en favor de la evolución. Al parecer, determinadas similitudes entre embriones de peces, aves, mamíferos y seres humanos demostrarían que todos ellos descenderían de antepasados comunes parecidos a los peces. <span>Darwin </span>lo explicaba así:

"De dos o más grupos de animales, aunque difieran mucho entre sí por su conformación y costumbres en el estado de adultos, por las fases de embrionarias muy semejantes, pueden estar seguros de que todos ellos son descienden de una misma forma madre y, por que tienen estrecho parentesco. Así, pues, la comunidad de la estructura embrionaria revela la comunidad de origen; [...] La embriología aumenta mucho el interés cuando se considera el embrión como un retrato, más o menos borroso, el progenitor de todos los miembros de una sola gran clase "
