What kind of monomers make up lipids
bogdanovich [222]

The kind of monomers that make up the lipids are the fatty acid and the glycerol.

Lipids or the fats are the organic compounds containing two kinds of monomers called the fatty acid and the glycerol. Fatty acids are the carboxylic acids made up of a hydrocarbon chain with a terminal hydroxyl group. Glycerol is an alcohol containing three carbon, five hydrogen and multiple hydroxyl groups (usually three) and it forms the back bone of all the lipids. The most abundant lipid called the triglycerides are the esters of fatty acids and glycerol.

The conversion of malate to oxaloacetate in the citric acid cycle takes place with the conversion of NAD to NADH. In this reacti
Mariana [72]

Answer:

a) the oxidizing agent.

Explanation:

In the citric acid cycle, malate is dehydrogenated into oxaloacetate and the reaction is catalyzed by malate dehydrogenase. The released electrons are accepted by NAD+. So, NAD+ is reduced into NADH. The substances that accept electrons during chemical reactions and are reduced to oxidize the other substances are called oxidizing agents. NAD+ serves as an oxidizing agent as it accepts electrons to oxidize malate into oxaloacetate.

Which traits are challenges of life for all organisms? Choose all answers that are correct.
Varvara68 [4.7K]
<span><span>a.   </span>Reproducing</span>
d. maintaining structure
f. obtaining energy

These three traits definitely standout as a challenge for every living creature in the ecosystem. In Darwin’s Natural Selection Survival of the fittest: being fit is one category in order to survive the wild, in other words, being flexible. Reproduction is battle royale in both humans and animals, even for plants too. Why? Because the ecosystem changes, the weather changes, the food chain is a combat to chase. Some can’t even reproduce due to hereditary or physical causes. Energy is as important as living. If plants can make their own food how about the carnivores and the omnivores. Food is a challenge. Structure is sustaining the capacity and ability to hunt and survive. Important and a by-product of obtaining energy.

C. How is the energy produced by respiration stored?
Fudgin [204]

Answer:

Energy produced by respiration is stored in Adenosine triphosphate, also known as ATP.

Explanation:

Cellular respiration uses glucose and turns it into ATP. Using NADH and FADH₂ (Created in the Krebs Cycle) in the Electron Transport Chain, we can produce 32-38 molecules of ATP. ATP carries a lot of energy, and your cells and body uses ATP (ATP is basically like a large battery).
