biology chapter 8 section 1
energy
ability to do work
metabolism
all chemical reactions in a cell
photosynthesis
anabolic pathway in which light energy from the sun is converted to chemical energy for use by the cell
classify the synthesis protein from amino acids as anabolic or catabolic explain?
anabolic, build things smaller to large.
the organisms in this groupB tree shrubs and grass are called _____________ .
autotrophs
what are the basic components of ATP?
biological energy that provides energy. adenine structure/group. ribose sugar, 3 phosphate group .
adenosine triphosphate
biological molecule that provides chemical energy
what is the first law of thermodynamics?
called the law of concentration/ energy cannot be created or destroyed
cellular respiration
catabolic pathway in which organic molecules are broken down to realse energy for use by the cell
difference between catabolic pathways and anabolic pathways.?
catabolic pathways is cellular respiration/ breaks down large molecules into smaller particles anoblic pathways is photosynthesis/ uses energy to build large molecules from small molecules
these organisms are called _________
chemautotrophs
2nd law of thermodynamics
energy cannot be converted without the lose of usable energy/entropy increase
this group must eat other organisms for food is ___________.
group A mice deer seed eating birds
the that makes their own food is ___________.
group B grass shrubs and trees
this organisms in group A deer mice and seed eating birds are called_________.
heterotrophs
1st law of thermodynamics
law of concervation of energy/ engery cannot be created or destroyed
autotroph
organism that makes its own food
heterotroph
organism that need to digest food in order to obtain energy
what are the 2 different types of autotroph
1.chemoautotroph they use inorganic substances such as hydrogen sulfide such as hydrogen sulfide 2. photoautotroph they convert energy from the sun into chemical energy
metabolic pathway
series of chemical reactions in which the product of one reaction is the substrate for the next reaction
sunlight
source of nearly all energy for life
thermodinamics
study of the flow and transformation of energy
