In the skeletal muscle cells of vertebrates, as many as ____________ molecules of atp are produced from one molecule of glucose.

shusha [124]

In the skeletal muscle cells of vertebrates, as many as 38 molecules of ATP are produced from one molecule of glucose. This is less than might be expected, because electrons from NADH produced during glycolysis must be shuttled through the inner mitochondrial membrane at a cost.
The energy of the electrons can be used to make ATP and in eukaryotes, glycolysis occurs in the cytosol, outside mitochondria.

One negative side effect of with anaerobic synthesis of energy is that a by-product of glycolysis is ________.

dem82 [27]

One negative side effect of with anaerobic synthesis of energy is that a by product of glycolysis is lactic acid

lactic acid cause muscle fatigue and post exercise muscle soreness. when you exercise the body uses oxygen to break down glucose for energy. when one do intensive exercise, oxygen may not be enough therefore lactic acid is produced.

n cattle, an autosomal mutation called Dexter produces calves with short stature and short limbs. Embryos that are homozygous fo

timofeeve [1]

Answer:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Explanation:

Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.

Roan are also heterozygous.

If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.

If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.

Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.

Crossing the two: DdRr x DdRr

Progeny:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Others that are either aborted or stillbirths include:

1 ddRR

2 ddRr

1 ddrr
