The major components of tendons, ligaments, and muscles are? a. proteins b. carbohydrates c. fats d. fiber
Hunter-Best [27]

The major components of tendons, ligaments, and muscles are proteins.

Hence, option A is correct answer.

<h3>What is Pyruvate Dehydrogenase? </h3>

The reaction between pyruvate and a lipoamide, which results in acetylated dihydrolipoamide and carbon dioxide, is catalysed by the enzyme pyruvate dehydrogenase. Thiamine pyrophosphate is a coenzyme needed for the conversion.

The pyruvate dehydrogenase complex changes the chemical pyruvate, which is created when carbohydrates are broken down, into the molecule acetyl-CoA. The chain of chemical events that provide energy for cells must start with this conversion.

<h3>What is glycolysis? </h3>

The metabolic process that changes glucose into pyruvate is known as glycolysis. The high energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process. A series of ten enzyme-catalyzed processes make up glycolysis.

Not producing adenosine 5′-triphosphate is not the primary goal of glycolysis; rather, it is to produce pyruvate for the trichloroacetic acid (TCA) cycle. 

By raising the proportion of NADH, a reduced form of NAD+ (nicotinamide adenine dinucleotide), to NAD+, the glycolytic synthesis of pyruvate lowers the cytosol.

erastova [34]

Answer:

22 mu

Explanation:

Since maximum number of flies are observed with +pb and s++ phenotype, they are the parental combinations.

Minimum number of flies are observed with +p+ and s+b phenotype hence they are the result of double crossover.

Gene order would be +bp and s++ since it is the only case which would lead to production of above mentioned double crossover. Hence gene b is in the middle of genes s and p.

Single cross over between genes s and b will give progeny +++ and sbp.

Map distance between s and b loci = recombination frequency =

(number of recombinants/ total progeny)*100

= [(single cross over between s and b + double crossover)/total progeny]*100

= [(102+106+7+5/1000]*100

=(220/1000)*100

=0.22*100

=22 mu

Which of the following is not a product of the light reactions of photosynthesis? 1) NADPH 2) NADH 3) ATP 4) Oxygen
n200080 [17]

Answer:

The correct option is number 2. NADH is not  product of light reactions of photosynthesis.

Explanation:

The light energy from the sun is captured by the pigmented molecule, chlorophyll, of the plants. This light energy is converted into chemical energy by a serious of light-dependent reactions. The main products of light-dependent reactions are the energy molecule ATP and NADPH. Oxygen is released as a by-product during photosynthesis. Hence, all the option 1,3 and 4 are produced during the light reactions except for option 2 i.e NADH.

Which process has most likely occurred when new traits appear in a species?
nata0808 [166]

Answer:Mutations in these genes can produce new or altered traits, resulting in heritable differences (genetic variation) between organisms. ... Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.
