In the citric acid cycle (also known as the krebs cycle), acetyl coa is completely oxidized. from the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of the citric acid cycle. adp, atp, pyruvate, o₂, h₂0, acetyl coa, nadh, nad⁺, glucose, coenzyme a, co₂

Net inputs- Acetyl CoA, NAD+, ADP

Net outputs- CO2, NADH, ATP

Explanation:

Pyruvate produced during glycolysis must first be decarboxylated and oxidized to produce Acetyl (a 2- carbon compound) before the kreb's cycle can commence.

The Acetyl group is attached to a carrier molecule known as coenzyme A to form Acetyl CoA, which undergoes oxidation and transfers its acetyl group to oxaloacetate(4-carbon) to form citrate (6-carbon).

Electrons are passed to NAD+ during the cycle to reduce it to NADH (3 molecules in total), which enters into the Electron transport chain as an hydrogen carrier (reducing agent).

A decarboxylation reaction involving isocitrate (6-carbon) occurs, which triggers the release of CO2 molecule, producing alpha-ketoglutarate (5-carbon).

The energy released when succinyl CoA is broken down into succinate is enough to power the substrate level phosphorylation (addition of inorganic phosphate) of ADP to ATP.

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.
