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
