What key macromolecules are made out of carbon? (hint: carbohydrates and lipids are two of the molecules)

Key macromolecules that are made out of carbon are carbohydrates, proteins, lipids, nucleic acids, etc., and all these molecules are made up of carbon and other molecules and make different bonds.

Carbohydrates are the most abundant macromolecules made out of carbon and are composed of carbon, hydrogen, and oxygen and play a critical role in energy storage and metabolism, and they also serve as structural components in some organisms. Lipids are macromolecule and serve a variety of functions in living organisms, including energy storage, insulation, etc., proteins are macromolecules composed of chains of amino acids that catalyze chemical reactions while providing structural support, and nucleic acids contain genomic information such as DNA and RNA.

Hence, key macromolecules that are made out of carbon are carbohydrates, proteins, lipids, and nucleic acids.

Newborn babies and hibernating animals contain a large amount of brown adipose (fat) tissue (BAT). Certain proteins in the BAT cells increase the permeability of the inner mitochondrial membrane to protons, disrupting the proton gradient. Which of the following best predicts the effect of disrupting the proton gradient in BAT?
А. The pH of the matrix will increase, allowing the production of more ATP per gram of substrate.
B. The pH of the intermembrane space will decrease, allowing a steeper proton gradient to form.
С. Electron transport and oxidative phosphorylation will be decoupled, generating more heat but less ATP.
D The number of protons available to pass through ATP synthase will increase, resulting in more ATP.

During the hottest months of summer, ewes (females) and lambs come to waterholes almost daily. The male sheep (rams) sometimes do not come to water for nearly a week at a time. Rams may roam 20 miles (32 kilometers) away from the available water supply. Add 20 miles (32 kilometers) to the approximately 5 miles (8 kilometers) traveled per day, and rams may travel almost 75 miles (120 kilometers) before they drink again. Rams are believed to drink approximately 4 gallons (15.2 liters) of water when they do come to water, while a ewe drinks approximately 1 gallon (3.8 liters) and a lamb drinks 2 pints (940 milliliters).


Questions:
1. How many miles to the gallon or kilometers per liter (of water) does a ram get?
2. How many gallons (or liters) of water would a ram drink in a month?
3. How many gallons (or liters) of water would a ewe drink in a month?

Question 27:
Critical Reading
Read these passages from the text and answer the questions that follow.
Fermentation
An important way of making ATP without oxygen is called fermentation. It involves glycolysis but not the other two stages of aerobic respiration. Many bacteria and yeasts carry out fermentation. People use these organisms to make yogurt, bread, wine, and biofuels. Human muscle cells also use fermentation. This occurs when muscle cells cannot get oxygen fast enough to meet their energy needs through aerobic respiration. There are two types of fermentation: lactic acid fermentation and alcoholic fermentation. Both types are described below.
Lactic Acid Fermentation
In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. In the process, NAD+ forms from NADH. NAD+, in turn, lets glycolysis continue. This results in additional molecules of ATP. This type of fermentation is carried out by the bacteria in yogurt. It is also used by your muscle cells when you work them hard and fast.
Did you ever run a race and notice that your muscles feel tired and sore afterward? This is because your muscle cells use lactic acid fermentation for energy. This causes lactic acid to build up in the muscles. It is the buildup of lactic acid that makes the muscles feel tired and sore.

Alcoholic Fermentation
In alcoholic fermentation, pyruvic acid changes to alcohol and carbon dioxide. NAD+ also forms from NADH, allowing glycolysis to continue making ATP. This type of fermentation is carried out by yeasts and some bacteria. It is used to make bread, wine, and biofuels.

Alcoholic fermentation produces ethanol and NAD+. The NAD+ allows glycolysis to continue making ATP.
Have your parents ever put corn in the gas tank of their car? They did if they used gas-containing ethanol. Ethanol is produced by the alcoholic fermentation of glucose in corn or other plants. This type of fermentation also explains why bread dough rises. Yeasts in bread dough use alcoholic fermentation and produce carbon dioxide gas. The gas forms bubbles in the dough, which causes the dough to expand. The bubbles also leave small holes in the bread after it bakes, making the bread light and fluffy.

Questions
1. What is fermentation?



2. Why is NAD+ so important in fermentation?




3. Both lactic acid fermentation and alcoholic fermentation begin with the same molecule. What is that molecule and where did it come from?



4. Why is bread light and fluffy?




5. Why do your muscles get sore after intense activity?
