What are the 3 parts of the cell theory
1. all living things have 1 or more cells
2. cells are the building blocks of life 3. all new cells come from pre-existing cells |
What is facilitated diffusion
allows molecules to pass through the cell membrane using transport proteins (carrier proteins, channel proteins)
|
What did robert hooke do for cell biology
he was fist to see cork cells with a microscope
|
What is the difference between active and passive transport
active requires energy, (ATP), and active goes against the concentration gradient while passive does not
|
What are the two things mitochondria need for cellular respiration and where does our body acquire these things
oxygen and small molecules, from glucose, from breathing and eating
|
|
What is a macromolecule
important substances that form when small molecules join
|
What is cellular respiration
series of chemical reactions that convert the energy in food molecules into a useable form of energy called ATP
|
Why is water an ideal solvent
it has positive and negative ends
|
What is the reason why energy is needed in active transport
it goes against the concentration gradient
|
What is know the three stages of cellular respiration, where they are in the cell, and how much ATP each stage creates
Glycosis creates 2 ATP in the cytoplasm. Broken down glucose Krebs Cycle and Electron Transport takes place in the mitochondria producing 34 ATP
|
|
What is nucleic acid
when long chains of nucleotides join, contain genetic info
|
What is photosynthesis
chemical reactions that convert light energy, water, and carbon into glucose and ozygen
|
How does cilia and flagella enable cells to move
they are inserted in specialize groupings called basal bodies and they direct the flow of substances
|
What is hypotonic, hypertonic, and isotonic. what effect does it have on the cells and stuff
hypotonic: causes swelling
hypertonic: causes he concentration/shrinks isotonic: environments show no effect on cells/not helpful when preserving food |
What is the photosynthesis/ ft. plants formula
light + 6 H2O + 6 CO2----}C6H12O6 + 6 O2
|
|
What is protein
long chain of amino acid molecules, do nearly everything for the cell including breaking down nutrients
|
What is a carbohydrate
made of sugar molecules, store energy, provide structural support, needed for communication
|
What is the difference between a plant and animal cell
plants have cell walls, chloroplasts, and central vacuoles, and an animal cell des not have a cell wall, it is usually a weird shape, and plastids are absent
|
What is the role of endocytosis and exocytosis in cell transport
endocytosis sends contents in and exocytosis sends them out
|
How is cellular respiration and photosynthesis similar
they are not similar they are opposites that just work together
|
|
What is active and passive transport
active is substances moving from high to low concentration and passive is substances through a cells membrane without using a cells energy
|
What is a please skip 69
please skip
|
What is the difference between a prokaryotic and a eukaryotic cell
eukaryotic has membrane bound organelles, prokaryotic does not
|
What is the formula for cellular respiration
C6 H12 O6 + 6O2---} 6 H2O + 6 CO2 + energy
|
What are the 2 fermintations
alcohol fermentation
lactic acid fermentation |
