Answer:
Explanation:
Two of the most important and widespread vitamin-derived coenzymes are nicotinamide adenine dinucleotide (NAD) and coenzyme A. ... When NAD loses an electron, the low energy coenzyme called NAD+ is formed. When NAD gains an electron, a high-energy coenzyme called NADH is formed.
Saturated fats are solid at room temperature, while unsaturated fats are liquid at room temperature. This is because saturated and unsaturated fats differ in their chemical structures.
Saturated fats have no double bonds between the molecules , which means there are no gaps and the fat is saturated with hydrogen molecules. Unsaturated fats have double bonds, which break up the chain of hydrogen molecules and create gaps, allowing the fats to liquefy at room temperature.
Saturated fats are found mainly in animal food such as meat and dairy products, while unsaturated fats are found in plant food and fish.
Answer:
B. an amino terminal signal peptide
Explanation:
The reactions of the citric acid cycle occur in the matrix of mitochondria. Therefore, all the enzymes required for this pathway are present in the matrix of mitochondria. These enzymes are formed on the ribosomes present in the cytosol and are transported into the mitochondria with the help of cytosolic heat shock proteins. The newly formed mitochondrial proteins have signal sequences present at their N terminal. The proteins to be transported into the matrix have a single signal sequence that at N terminal which is removed by a protease once the enzyme enters into the matrix.
Answer:
25%
Explanation:
This cross involves a single gene coding for spot color in beta fish. Green allele is C while the blue allele is c. This gene exhibits co-dominance, hence, an heterozygote beta fish (Cc) i.e. combination of both alleles, will have both phenotypes expressed to form a green and blue spotted beta fish.
If two green and blue spotted beta fishes (Cc) are crossed, each beta fish will produce gametes with C and c alleles. Using these gametes in a punnet square, four possible offsprings with the following genotypes will be produced: CC, Cc, Cc and cc.
C c
C CC Cc
c Cc cc
Hence, the percentage of offsprings expected to be green (CC genotype) is 1 out of 4possible offsprings i.e. 1/4 × 100 = 25%
