How many carbons are in cholesterol Of these how many are not contained in the rings?
There are 27 carbon atoms in a molecule of cholesterol. 10 are not contained in the rings.
How do you write the formula of a monosaccharide that has three carbons?
The general formula for a monosaccharide with three carbons is C3H6O3. One example of a monosaccharide with three carbons is glyceraldehyde, which has the molecular formula C3H6O3.
What are tertiary carbons?
Tertiary carbons are carbons that are directly bonded to three other carbon atoms in a molecule. They are typically more sterically hindered and less reactive compared to primary or secondary carbons due to the presence of three alkyl groups.
What is the product of pyruvate processing?
Acentyl CoA
What are the products of pyruvate oxidation?
acetyle-CoA NADH CO2 hydrogen ion
How many carbons depart during the preparation steps and the cycle proper during the second stage of aerobic respiration?
During the second stage of aerobic respiration (Krebs cycle), two carbons are removed in the form of carbon dioxide at each turn of the cycle. This occurs during the conversion of isocitrate to alpha-ketoglutarate and then from alpha-ketoglutarate to succinyl-CoA.
What are the three inhibitors of tca cycle?
1.) Increases in NADH, Succinyl CoA, ATP, Citrate inhibit citrate synthase. 2.) Increases in ATP will inhibitisocitrate dehydrogenase. 3.) Increases in succinyl CoA and NADH will inhibit succinate thiokinase.
How many of the carbons originally present in acetyl CoA continue on to respiration after the Krebs cycle?
Two carbons from acetyl CoA continue on to the Krebs cycle. These two carbons are eventually released as carbon dioxide during respiration, while the remaining two carbons are used to regenerate oxaloacetate to complete the cycle.
How many acetyl CoA molecules may be obtained from oxidation of a 16-carbon fatty acid?
A fatty acid that contains 20 carbons will yield 10 molecules of acetyl-CoA. Acetyl-CoA is also referred to as acetyl coenzyme A.
What forms when Coenzyme A attaches to two carbons from pyruvic acid acid?
Acetyl-CoA forms when Coenzyme A attaches to two carbons from pyruvic acid. This is a crucial step in the process of cellular respiration, as acetyl-CoA enters the citric acid cycle to generate energy for the cell.
What is the functional difference of Succinyl CoA synthase in plant and animal?
In plants it is metabolized from photosynthesis to form chlorophyll.In animals it is metabolized in the form of energy originating from the liver.
How many ATP molecules could be made through substrate-level phosphorylation plus oxidative phosphorylation chemiosmosis if you started with three molecules of succinyl CoA and ended with oxaloaceta?
From one molecule of succinyl CoA, substrate-level phosphorylation generates 1 ATP, whereas oxidative phosphorylation chemiosmosis produces approximately 12 ATP. Therefore, for three molecules of succinyl CoA, a total of 39 ATP molecules could be produced (3 ATP from substrate-level phosphorylation and 36 ATP from oxidative phosphorylation chemiosmosis).
How many carbons from 1 glucose molecule enter 1 round of the Krebs cycle?
Two carbons from one glucose molecule enter one round of the Krebs cycle in the form of acetyl-CoA, which is derived from pyruvate through pyruvate dehydrogenase.
List the steps of the Krebs cycle?
Acetyl-CoA combines with oxaloacetate to form citrate. Citrate is converted into isocitrate. Isocitrate is oxidized to alpha-ketoglutarate, generating NADH. Alpha-ketoglutarate is converted to succinyl-CoA, generating NADH and ATP. Succinyl-CoA is converted to succinate, producing GTP. Succinate is converted to fumarate, generating FADH2. Fumarate is converted to malate. Malate is converted back to oxaloacetate, generating NADH and completing the cycle.
What forms when Coenzyme A attaches to 2 carbons from pyruvic acid?
Acetyl-CoA is formed when Coenzyme A attaches to 2 carbons from pyruvic acid. Acetyl-CoA is an important molecule that enters the citric acid cycle to produce energy through the oxidation of acetyl groups.
How many carbons does glucose have?
6 carbons 6 carbons
How many carbons are in alpha ketoglutarate?
5 carbons
