Gas exchange involves the transport of two respiratory gases, oxygen and carbon dioxide. Match each statement into the appropriate items whether it applies to oxygen only, carbon dioxide only, or both oxygen and carbon dioxide.

a. Net diffusion from alveoli capillaries
b. Waste product of cellular respiration
c. Sometimes transported as bicarbonate
d. Net diffusion from lung capillaries to alveoli
e. Net diffusion from body tissues blood
f. Enters alveoli during inhalation
g. Required for cellular respiration
h. Transported by hemoglobin

Answers

Answer 1

Answer:

a. both oxygen and carbon dioxide

b. carbon dioxide only

c. carbon dioxide only

d. oxygen only

e. carbon dioxide only

f. oxygen only

g. oxygen only

h. oxygen only

Explanation:

This question is describing the gaseous exchange of carbon dioxide and oxygen that occurs during cellular respiration. The gaseous exchange occurs via a structure called ALVEOLI OR AIR SAC.

According to this question, the following statements in the question will be matched with whether it applies to oxygen only, carbon dioxide only, or both oxygen and carbon dioxide:

a. Both oxygen and carbon dioxide are diffused through the alveoli capillaries.

b. Carbon dioxide is the waste product of cellular respiration (excreted via the lungs).

c. Carbon dioxide have the ability to form carbonates (CO3²-) and are sometimes transported in that form.

d. Oxygen from the lungs diffuse into the alveoli during inhalation.

e. Carbon dioxide from the body tissues are carried by the blood into the alveoli in order to be transported out of the body.

f. Inhalation is the taking in of air (oxygen-containing). Hence, oxygen only enters alveoli during inhalation.

g. Oxygen is the necessary substance needed by cells in order to perform cellular respiration (aerobic).

h. Haemoglobin is an iron-based protein present in the blood cells. It possess affinity for oxygen and carries oxygen in the blood.

Answer:

d all of the above :)

Explanation:

hope this helped

Answer:

D) All of the above.

Explanation:

The Shape of a solid does not change (with exceptions), and the atoms typically remain static with little freedom of movement.

The volume of the solid also stays exactly the same if no external adjustments are made.

The arrangements of atoms & molecules are definitive and packed together, giving little movement, therefore allowing the solid to keep form.

How does aerobic respiration differ from anaerobic respiration ?
I need long answer, and correctly explained.​

Answers

Answer:The difference between aerobic and anaerobic respiration.

Aerobic respiration  Anaerobic respiration

1. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen. 1. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen.

2. It includes glycolysis, citric acid cycle and oxidative phosphorylation. The first two processes take place in the cytoplasm while last one occurs in mitochondria. 2. Glycolysis is followed by ethanol fermentation (occurs in yeast) or lactic acid fermentation (in muscles and microbes like lactic acid bacteria).  

3. The end products are carbon dioxide and water. 3. End products of ethanol fermentation are ethanol and carbon dioxide; that of lactic acid fermentation are lactic acid

4. Owing to complete oxidation of glucose, a large amount of energy is produced (36-38 ATP molecules) 4. Incomplete oxidation of glucose does not release all stored energy and only 2 ATP molecules are produced.

Anaerobic respiration is carried out by yeast and other anaerobic organisms like lactic acid bacteria, E. coli, Staphylococcus, Clostridium etc.

Explanation:

EVOLUTION CONNECTION The result of mitosis is that the daughter cells end up with the same number of chromosomes that the parent cell had. Another potential way to maintain the number of chromosomes would be to carry out cell division first and then duplicate the chromosomes in each daughter cell. Do you think this would be an equally good way of organizing the cell cycle

Answers

Answer:

No, because it would lead to chromosome mosaicism  

Explanation:

Chromosomal mosaicism can be defined as the presence of two or more cell populations with a distinct number and/or type of chromosomes in the cells of an organism. If the cell would split before chromosome duplication, it would lead to the fact that some cells would have one chromosome of the homologous pair being duplicated, while other cells would have duplicated the other one. In consequence, this process would produce a genomic imbalance between different cell populations that would be expected to be lethal for the organism.

Propose a series of equations to represent the equilibria described in the prelab discussion involving the transport of oxygen from the lungs to the cells and the carbon dioxide back to the lungs.
