Discuss the importance of cellular respiration in living organisms. How does it relate to energy production and consumption?

Organisms that break down dead or decaying matter are known as .

The first step in the process of photosynthesis converts light energy into .

What molecule is often referred to as the ‘energy currency’ of the cell?

Sar1 is activated by:

Vesicles leaving the trans-Golgi network and heading to endosomes or lysosomes are formed by which of the following coat proteins?

Identify which coat proteins are used for the following vesicles trafficking through the endomembrane system below.  For answers use A, B, or C only. A = COP I B = COP II C = Clathrin D = unkown coat protein Vesicles leaving the rough ER for the Golgi network Retrograde vesicles moving between cisternae of the Golgi network Retrograde vesicles moving from the Golgi to the ER Vesicles leaving the Trans-Golgi network for endosomes or lysosomes Vesicles leaving the Trans-Golgi network  for the cell membrane  

People with Barth syndrome have a mutation in the TAZ gene, which encodes the tafazzin protein. Mutated tafazzin disrupts the mitochondrial membrane and, subsequently, the electron transport chain in the membrane. Tafazzin mutations affect ATP production in Barth cells. Surprisingly, Barth cells still produce the same amount of ATP as normal cells. In order to compensate for tafazzin mutations that affect the efficiency of cellular ATP production, Barth cells have increased mitochondria and mitochondrial mass. Cells with mutated mitochondria may be less able to respond to stressors, leaving the cells vulnerable. Consider a person with Barth syndrome that has a TAZ mutation that causes a 60% reduction in ATP production. If a normal cell has 100 mitochondria, how many mitochondria would you expect in a Barth cell, assuming that ATP production increases proportionally with the number of mitochondria? If necessary, round to the nearest whole number.  Use a number, not a word to answer. There would be mitochondria
