In the lungs, what can affect the suface area

Answers

Answer 1
surfaces where O2 diffuses into the blood and CO2 diffuses out of the blood. Each lung contains millions of these sacs. The small round alveoli allow for an amazingly large surface area for this gas exchange to take place. ... Therefore, the greater the surface area, the more gas exchange can occur.

In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver. In the liver, lactate is converted back into glucose by gluconeogenesis.

Answers

Answer:

The correct answer is -

1. c. both

2. b. gluconeogenesis

3. d. neither

4. b. gluconeogenesis

5. a. glycolysis

6. c. both

7. a. glycolysis

8. d. neither

Explanation:

Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.

Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.

Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.

Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.

Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.

Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.

Explain how the body provides oxygen to our cells and removes the carbon dioxide waste. In your description, be sure to include the following terms: oxygen, carbon dioxide, heart, blood vessels, lungs, alveoli, and exchange of gases.

Answers

Answer:

The heart pumps blood through the lungs. In the lungs the blood receives oxygen and releases carbon dioxide. Then the heart pumps this oxygen-rich blood from the lungs to your cells. When the oxygen-rich blood gets to the cells, the cells receive the oxygen and release the carbon dioxide.

The cells in our bodies need oxygen to stay alive. Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.

How do animals and people get glucose?

Answers

Answer:

Animals obtain glucose by eating plants, and fungi and bacteria absorb glucose as they break down the tissues of plants and animals.

And for humans it mainly comes from foods rich in carbohydrates, like bread, potatoes, and fruit. As you eat, food travels down your oesophagus to your stomach. There, acids and enzymes break it down into tiny pieces. During that process, glucose is released.

Given that the function of egg yolk is to nourish and support the developing chick, complete the explanation of why egg yolks are so high in fat, protein, and cholesterol.

Answers

Answer:

Chick with in the egg depend for all its energy and food requirement on the egg yolk , therefore egg yolk is rich in fat, protein, and cholesterol.

Explanation:

Before the egg breaks and the chick comes out, few days nourishment for chicks is required. Hence, the egg yolk needs to be nutritious as new developing chick (with in the egg) rely for essential nutrients (required for growth) on the egg yolk. Chick require energy  from yolk, hence it is rich in fat (energy). It also needs to grow and develop, therefore egg yolk has lot of protein (building blocks). Lipid and cell with in the yolk help in formation of cell and strengthening of bones and feathers

Understanding the structural and molecular interactions that induce shape and function for a protein has been an obstacle for some of your students. You decide to plan a lesson to introduce them to the basic amino acid structure and then use that concept to introduce the different levels of protein structure. To reinforce your lesson on amino acids, you need to aid the students in understanding that most naturally occurring amino acids have a shared base structure. Each amino acid has an amine group, an alpha-carbon (or central carbon), an R-side group, and a carboxyl group. The R-side group is what gives each amino acid its distinctive characteristics--for example, whether the amino acid will be acidic or basic, hydrophilic or hydrophobic, or charged.
Choose the statement that does NOT pertain to amino acids.
a. All amino acids must contain a nitrogen-based molecule and a carboxylic acid.
b. Amino acids always contain a sulfur atom in their R-side group.
c. The groups composing an amino acid are located around a central alpha-carbon.
d. The R-side group will determine the overall chemical properties of an individual amino acid.

Answers

Answer:

b. Amino acids always contain a sulfur atom in their R-side group.

Explanation:

Amino acids are monomeric units of protein molecules. This means that a protein molecule is made up of a chain of amino acids. As stated in this question, an amino acid is structurally made up of a central carbon atom called α carbon, an amine group (-NH2), a carboxylic acid group (-COOH), and a R-group side chain, which distinguishes each amino acid from one another.

Based on this question, all amino acids must possess the following characteristics:

- must contain a nitrogen-based molecule (amine group) and a carboxylic acid.

- The groups i.e amine, carboxylic acid and R chain are located around a central alpha-carbon.

- The R-side group will determine the overall chemical properties of an individual amino acid i.e whether acidic, basic, hydrophilic etc.

However, considering the fact that the R side chain of individual amino acids are different from one another, not all amino acids will contain a sulfur atom in their R-side group. Note that, Methionine and cysteine are the two common sulfur-containing amino acids.
