The mitochondria has structures that act like what
Turbines
Anaerobic means
Without without oxygen
To harvest food energy during glycolysis what must be present as an electron acceptor
NAD+
What is photosynthesis
It’s a process whereby plants algae which are parties in certain bacteria transform light energy into chemical energy using carbon dioxide and water is starting materials
Photosynthesis implants and Audi occur within light absorbing organelles called what
Chloroplast
What is the light absorbing molecule in the chloroplasts that plays a central role in converting for energy into chemical energy
Chlorophyll
Carbon dioxide enters a leaf in oxygen exits by the way a tiny pores called the what
Stoma
Suspended in the stroma are interconnected membrane sax called the
Thylakoids
The thylakoids are concentrated in stacks called
Grana
What occurs into multistep stages
