Answer:

In a global sense, Cellular respiration takes place with the following process: Glycolysis, Pyruvate oxidation, Citric acid cycle (Kreb's cycle) and finally the oxidative phosphorylation. This corresponds to 12, 13, 11, 14, and 15.

Explanation:

First step: 12. Glycolysis takes place in the cytoplasm and breaks down glucose to form two molecules of pyruvate. 2 ATP are produced and NADH is saved for later.

Second step: 13. Two molecules of pyruvate move into the mitochondria where they are converted into Acetyl CoA. More NADH is produced and CO2 is released.

Third step: 1 1. In the Citric Acid/Kreb's Cycle the carbons that are left from the initial glucose are oxidized releasing more CO2. NADH and FADH2 and 2 ATP molecules are produced.

Fourth step: 14. In the electron transport chain, the NADH and FADH2 give up electrons, energy is released and captured as it moves from a high concentration to a low concentration.

Finally, 15. Energy is used to produce about 34 ATP. Oxygen is the terminal electron acceptor that combines with oxygen to produce water

We can conclude that Cellular respiration takes place with the following process: Glycolysis, Pyruvate oxidation, Citric acid cycle (Kreb's cycle) and finally the oxidative phosphorylation. This corresponds to 12, 13, 11, 14, and 15.

Answer:

The steps will be in order in the sequence 12,13,11,4 and 15

Explanation:

12. In glycolysis, glucose is converted into pyruvate. ATP and NADH ARE MADE.

13. Pyruvate is oxidized and converted into acetyl CoA in the mitochondria. Carbon dioxide and NADH are also made.

11. The acetyl CoA undergoes a series of changes and ATP, FADH2, NADH, and carbon dioxide are released.

4. NADH and FADH2 lose their electrons and get converted back into NAD+ and FAD.

15. Oxygen takes electrons and water is produced. 34 ATP molecules are released.

Answer:

It is usually easier to calculate an enzyme's reaction velocity from the rate of appearance of PRODUCT rather than the rate of disappearance of a SUBSTRATE. Enzyme activity is measured as an INITIAL reaction velocity, the velocity before much SUBSTRATE has been depleted and before much PRODUCT has been generated. It is easier to measure the appearance of a small amount of PRODUCT from a baseline of zero PRODUCT than to measure the disappearance of small amount of SUBSTRATE against a background of high concentration of SUBSTRATE.

Answer:

Inbreeding leaves animals susceptible to genetic disease, and populations to reduced fitness. This family of three would not be able to sustain a population given their a) group dynamics and b) genetic variation

Explanation:

In small populations, the variation in genetic material is likely to be low. The consequence of this is that there is increased homozygosity. That means less members of the population carry two different alleles of a gene for any given trait. This increases the chance of the appearance of recessive traits, which could be disease causing or otherwise reduce fitness.

With only three related individuals left, the chances of generating a new and thriving population with the limited genetic material is almost non existent, especially considering the animals are a male, female and their pup

IN THE LUMEN INSIDE OF THE ENDOPLASMIC RECTICULUM.

<u>Explanation:</u>

The endoplasmic recticulum is the continuous membrane system that forms that forms the more number of flattened within the cytoplasm of eukaryotic cells and performs the multiple process in the cell.

The immportant functions of endoplasmic recticulum is folding, synthesis, modification, ans transport of the protein. The lumen is the protein which is present in the endoplasmic recticulum.

The lumen of the endoplasmic recticulum is the area closed by the endoplasmic recticulum membrane, it is an extensive network of the membrane tubues, visicles, and flattened the cisternae found in the eukaryotic cells.
