2.8-Cell RespirationDraw and annotate a molecule of ATP to show how it stores ad releases energy -
answer During cellular respiration, an inorganic phosphate is added to ADP in order to
make ATP
List the three main cellular processes that use ATP as a source of energy - answer-
muscle contraction
-active transport
-protein synthesis
-vesicle transport
-cell signaling
-DNA/RNA replication
Define cell respiration - answer the controlled release of energy from organic
compounds in cells to form ATP
cell respiration is an example of a metabolic process. State the type of molecules that
control the process of respiration - answer enzymes
-everything that controls enzymes (PH, temp) also controls cellular respiration
Explain why cell respiration must happen within every living cell - answer-all cells (even
single-celled bacteria) need energy
Identify two organic molecules, other than glucose, which could be used for respiration -
answerlipids and proteins
Identify the two components of the cell in which respiration takes place - answer1) starts
in the cytoplasm=glucose is broken into pyruvate that goes into cytoplasm and produces
ATP, if pyruvate goes into mitochondria then the link and krebs cycle occur (aerobic
respiration), if pyruvate stays in the cytoplasm then fermentation occurs (anaerobic
respiration) and lactic acid is produced in humans
2) Mitochondria= Krebs cycle
distinguish between the terms aerobic and anaerobic - answeraerobic=with oxygen
anaerobic=no oxygen
Label the diagram of aerobic cell respiration below - answer-aerobic= oxygen and
pyruvate go into mitochondira
starts with Glucose and oxygen
-glucose is broken into pyruvate in the cytoplasm
-ADP is converted to ATP
