Structure of water and H bonding
What is a covalent bond?
Bond formed by the sharing of electrons by two atoms
How many macromolecules exist?
4
Prokaryotic and Eukaryotic
Definition of Photosynthesis
Organisms absorb energy from the sun to convert it into chemical energy of sugars
what is selective permeable?
Plasma membrane allows some substances to pass through but not others
what forms polar covalent bonds?
Hydrogen and Oxygen within water molecules
What are macromolecules made of?
monomers
Nucleus
Two stages of photosynthesis:
Light-dependent reactions and calvin cycle
Substances moving from high concentration to low is called?
Passive transport
Is water hydrophilic or hydrophobic?
Hydrophilic
Definition of hydrolysis is?
water added to break down a compound
What does the nucleus do?
Stores cell's DNA and directs synthesis of ribosomes and proteins
What are the results of the light-dependent reaction and how are they used in calvin cycle?
The results would be NADPH and ATP which are used as chemical reactions for the Calvin Cycle
Active transport requires energy.
True
What's cohesion?
Water molecules are attracted to each other
When amino acids attach to one another, what do they create?
Peptides
46
Is light required in the Calvin Cycle?
No
what is primary active transport?
Ions can move across membrane and creates a difference in charge of the membrane which is dependent on ATP
What are the states of water?
Gas, liquid, and solid
Name all 4 macromolecules.
Carbohydrates, proteins, lipids, and Nucleic acids
What's the unified cell theory?
All living things are composed of one or more cells, cell is the basic unit of life, and new cells arise from existing cells
Equation of Photosynthesis
6CO2+6H2O+sunlight->C6H12O6+6O2
Carbon dioxide+water+sunlight-> sugar+oxygen
Fluid Mosaic Model
