Predict what will happen to the concentration of pyruvate, NADH, and H+ when ATP synthase is stopped by oligomycin
The concentration of pyruvate and NADH does not no change, however the concentration of H+ increases.
Oligomycin is a toxic substance to humans, produced by bacteria of the Streptomyces type. It acts by blocking the proton channel in a region of the ATP synthase enzyme, inhibiting oxidative phosphorylation. Thus, the electron transport chain is slowed but not completely stopped.
Cellular respiration consists of a metabolic pathway that breaks down the glucose molecule to produce energy in the form of ATP. Stages of cellular respiration are:
GlycolysisPyruvate oxidationKrebs cycle or the citric acid cycleOxidative phosphorylationGlycolysis consists of the breakdown of glucose to form two pyruvate molecules, where energy is produced in the form of ATP and NADH. Then, pyruvate oxidation occurs, catalyzed by an enzyme called pyruvate dehydrogenase in the mitochondrial matrix. Next, is the Krebs cycle where energy is produced in the form of ATP and other biosynthetic reactions also occur where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol. Finally, oxidative phosphorylation takes place as a metabolic process that uses energy released by the oxidation of nutrients to produce ATP. It consists of two stages: in the first one, free energy generated by redox chemical reactions in various multiprotein complexes (electron transport chain) and produces an electrochemical gradient of protons (H+) across an associated membrane in a process called chemiosmosis. The respiratory chain consists of three main protein complexes (complex I, III, IV), and several "auxiliary" complexes, utilizing a variety of electron donors and acceptors. The three complexes associate in supercomplexes to channel electron transport molecules, coenzyme Q and cytochrome c, making the process more efficient. So, the proton gradient produced by proton pumping is used to make ATP molecules. Protons move through the ATP synthase down their concentration gradient into the matrix catalyzing the conversion of ADP to ATP.
Then, using oligocycin there will be no change in the concentration of pyruvate since the synthesis of it (from the breakdown of glucose) does not depend upon an ATP synthase. Also, there is no change in the concentration of NADH because it is oxidized and reduced via redox reactions which also does not depend on the enzyme. At last, there is an increase in the concentration of H+ (protons) because its gradient wont be use by the ATP synthase to make ATP molecules.

What description explains how a flower produces a seed? (2 points)
Group of answer choices
1.After the stamen produces pollen, the pollen is moved to the petal to produce a seed.
2.As pollen travels down the stamen, fertilization occurs and a seed is produced.
3.When the ovule receives pollen, fertilization occurs and a seed is produced.
4.When the stigma receives pollen, a seed is produced and then fertilization occurs.
Answer:
Pretty sure its #3
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. ... The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.
What was the style of the revival sermons?
Answer: To Revive or not to Revive? Exodus 32:19 In 1857 there was a 46 year old man named Jeremiah Lamphere who lived in New York City.

Why does wind erode the sand in deserts more than the dirt in forests?
There is less water in forests to keep the soil moist.
The dirt in forests is coarser than the sand in deserts.
Forests have larger rocks than deserts.
Deserts have less plant life to hold the soil in place.
Answer:
I think the answer is D
Explanation:
the tree roots helps to hold the dirt down plus the higher amounts od mositure make the dirt denser
Answer:Wind is a stronger erosional force in arid regions than it is in humid regions because winds are stronger. In humid areas, water and vegetation bind the soil so it is harder to pick up. In arid regions, small particles are selectively picked up and transported.
