In the absence of oxygen, what is the net gain of ATP for each glucose molecule that enters glycolysis?
Naily [24]

Answer:

2 molecules of ATP

Explanation:

Glycolysis is the anaerobic process (no oxygen required) used in the breakdown of glucose to extract energy. It occurs in the cytoplasm of both prokaryotic and eukaryotic cells. It is the first step of cellular respiration.

Glycolysis is subdivided into two phases: the first phase uses energy (ATP), while the second phase produces it together with pyruvate and NADH.

Two molecules of ATP are required for the first stage of glycolysis, while 4 ATP molecules and 2 NADH molecules are formed in the second stage.

Tanya [424]

Answer:

Explanation:

Since Mark's wife was a carrier, it means that she is heterozygous for the trait. And after Mark got tested, they decided to have children due to no increased risk if they do have children, it means the condition is not an autosomal dominant condition but a recessive condition because if the condition is dominant, only one copy of the affected allele is needed to increase risk.

Thus, with a no increased risk, it means Mark is normal i.e. carries no copy of the recessive allele.
