How Organisms Obtain Energy Flashcards
What is the study of flow and transformation of energy in the universe?
Thermodynamics
What are the two types of organisms?
Autotrophs and Heterotrophs
What are autotrophs?
organisms that make their own food
What are heterotrophs?
they ingest food for energy
What are the two types of autotrophs?
Chemoautotrophs and Photoautotrophs
What are Chemoautotrophs
use inorganic substances for energy
What are photoautotrophs?
convert light energy into chemical energy
What is metabolism?
chemical reactions in a cell/ digestion
What is metabolic pathway?
A series of chemical reactions where one reaction is the base of the next reaction.
What are the two types of metabolic pathway?
Catabolic and Anabolic pathway
What are catabolic pathways?
releases energy by breaking down large molecules to smaller ones
What are anabolic pathways?
using the energy from catabolic pathways, and building larger molecules from smaller ones
What are examples of catabolic and anabolic pathways?
Catabolic = Cellular Respiration and Anabolic = Photosynthesis
What is ATP?
most important molecule that provides chemical energy
What is ATP made of?
Adenine, Ribosome Sugar, and Phosphate group
