Answer:

peroxisome

Explanation:

Adrenoleukodystrophy (ALD) is a X linked recessive disorder. In this disorder, fatty acid beta oxidation occurring in peroxisomes is impaired which leads to the accumulation of long chain fatty acid in cells.

The disease is caused by mutation in gene ABCD1 which codes for peroxisomal membrane transporter. This transporter transports the long chain fatty acids inside peroxisome for degradation hence problem with it interferes with the degradation process leading to build up of fatty acids inside cells.

The main damage is caused to the myelin sheath of the nerves which leads to hyperactivity and seizures. Other symptoms are speaking and listening problems, muscle stiffness, sexual dysfunction etc.

raketka [301]

Answer:

B) The rates of ATP production and carbon dioxide production would both increase.

Explanation:

The citric acid cycle is the second stage of aerobic cellular respiration. It includes complete oxidation of acetyl CoA into CO2 and H2O. During the citric acid cycle, NAD and FAD serve as electron acceptors. Reduction of these reducing powers forms NADH and FADH2 which in turn enter the electron transport chain for their oxidation and drive the process of as many as 32 ATP molecules by oxidative phosphorylation. On the other hand, fermentation forms of 2 ATP molecules and a few or no CO2 molecules.

Therefore, if one of the eight intermediates of the citric acid cycle is added to the medium, the yeast cells would perform aerobic cellular respiration and would form more CO2 and ATP molecules than the ones formed during the process of fermentation.

The general function of an enzyme in the body is to ________. The general function of an enzyme in the body is to ________. elim
bixtya [17]

Answer:

catalyze chemical reactions

Explanation:

An enzyme is a proteinous substance that acts as biological catalysts and increases the rate of biochemical reactions in the body. Enzymes are specific in nature which is as a result of the structure/shape of its building block (amino acid).

Enzymes speedens the rate of a chemical reaction in living systems, which would normally not occur or occur at a much slower rate, without the presence of an enzyme. Enzymes acts on the reactants called Substrates by binding to them to form products but they are not used up in the reaction. Hence, enzymes are not reactants.

Match each component of biodiversity to the example of how it contributes to ecosystem stability.
professor190 [17]

Answer:  

Genetic diversity: Some individuals in a population of wild rabbits are resistant to a new disease.

Ecosystem diversity: If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks.  

Species diversity:  Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation.  

Biodiversity of an ecosystem is usually explored by three diversities which are responsible for ecosystem stability they are : genetic diversity, ecosystem diversity and species diversity.

Genetic diversity is the variety of genes within a population of species. Each species consists of individuals bearing different genetic composition. Some individuals in a population of wild rabbits are resistant to a new disease because they exhibit genetic diversity within the population as a consequence some individuals exhibit genes which protect them against new disease.

Species diversity is the variety of species within an ecosystem. Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation is an example of species diversity. The wild rabbits from a forest and a neighboring meadow are two species living in an ecosystem stating the diversity of species in an ecosystem.

Ecosystem diversity is the variety of ecosystems in a given region.If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks is an example of ecosystem diversity because in an ecosystem there is interaction of organisms as predator prey relationship. This example is also relating with predator prey relationships in an ecosystem.

Part c addition of a nucleotide into a dna strand is an endergonic reaction. what provides the energy to drive the reaction
fredd [130]
<span>The energy to this reaction can be provided by adding a catalyst enzyme : DNA polymerase. Energy is released when this enzyme cuts off 2 phosphate groups from the end of the nucelotide. This energy is sufficient to link the nucleotide to the DNA.</span>

9. Look closely at the illustration above. a. What process is occurring? b. What is being made? c. How can you tell?
mars1129 [50]
The answers are:

A. DNA replication in the nucleus of a cell
B. From one helix of DNA in a replication process, we get two: The DNA is a double helix and it consists of two strands of specifically connected amino-acids. When the time for replication comes, a set of enzymes unwind the two strands and leave them as a base for additional two strands attaching to them - the green line is an example of that. The free nucleotides - adenine, guanine, thymine and cytosine are left open and the enzyme called DNA-polymerase helps to produce a new strand on the template of the old parental one (one of the blue ones in the picture) 
C. By the location on the smaller picture - replication takes place in the nucleus. And the most important hint are the letters A - adenine, G - guanine, T- thymine, and C-cytosine. A connects with T, and G connects with C.
