The majority of CO₂ produced from cellular respiration is released during the citric acid cycle.

Unicellular organisms, like bacteria, only use cell division for growth and development. 

When does substrate-level phosphorylation occur during cellular respiration?

About 90% of the ATP made during cellular respiration are created during glycolysis and the citric acid cycle. 

The mechanism of photophosphorylation is most similar to which of the following processes?

A horse trots in a perfect circle around its trainer at the end of a 19-foot-long rope. How far does the horse travel as it circles the trainer once? 

The measures of two angles of ABC (shown in the illustration) are given. Find the measure of the third angle, if  m(∠A) = 130.3º and m(∠B) = 40.3º.  

A sample of solid sodium bicarbonate, NaHCO3,  is placed in a closed 1.0 L vessel at 398 K and allowed to decompose unil it reaches equilibrium according to the following equation:                                         2 NaHCO3 (s)   ⇌  Na2CO3(s) +  H2O (g)   +  CO (g)      Kp = 0.250 What is the partial pressure of CO (in atm)  at equilibrium?
