Why is pyruvate converted to lactate in anaerobic conditions?

1 answer:

3 0

Because there is a lack of sufficient oxygen in muscle cells. For muscle cells to convert pyruvate into usable energy (ATP), there must be a sufficient amount of oxygen available to the cells. When there is not, the body has the ability to convert it to lactate which can provide energy when little oxygen is available.

The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability

Zinaida [17]

Answer:

Explanation:

Let the ability to break down the red color in beets be represented by the allele B. The inability would be represented by the allele b.

A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.

A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:

Bb x Bb

BB 2Bb bb

(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.

Probability of having a girl = 1/2

Probability of being a secretor = 1/4

probability of their first child will be a secretor girl = 1/2 x 1/4 = 1/8

(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.

Probability of having a girl = 1/2

Probability of being a nonsecretor = 3/4

Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor = 1/2 x 3/4 = 3/8

2. Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.

= 3/4 x 3/4 = 9/16

Blood is often collected in what capillary tubes rather than plain capillary tubes to prevent clotting of the blood

motikmotik

The blood is collected in heparinized capillary tubes to prevent clotting. Heparin is a blood thinner and this anticoagulant is produced naturally by mast cells and basophils. But heparin can not dissolve or break the preformed clots.
