QUIZ REVIEW Flashcards
Formula for Photosynthesis
Water 6 H2O + Carbon Dioxide 6 CO2 –> Glucose C6 H12 O6 + Oxygen 6 O2
Formula for cellular respiration
Glucose C6 H12 O6 + Oxygen 6 O2 –> Water 6 H2O + Carbon Dioxide 6 CO2
What are active transports
Active transports are when molecules move from a low to high concentration gradient.
What are passive transports
Passive transports are when molecules move from a high to low concentration gradient.
Do active transports require energy and are they moving with or against the gradient?
Active transports require energy and they move against the concentration gradient
Do passive transports require energy and are they moving with or against the gradient?
Passive transports do not require energy and they move with the concentration gradient
What is an example Passive transport?
H2O or OXygen through the cell membrane
What is an example active transport?
the Potassium-Sodium pump, Endo or exocytosis
What are phospholipids and what interacts with them?
Phospholipids act as a bi-layer for the cell which small uncharged molecules and hydrophobic molecules can move inside them, and cholesterol, proteins, and carbohydrates can interact with them
What does cholesterol do?
Cholesterol makes the cell fluid at a balanced amount, not too firm or fluid
What do carbohydrate chains do?
They can send signals, make cells stick to each other, and help with cell recognition
What do proteins do?
Transport proteins (Sodium-Potassium pump), Help with hormones, enzymes, and help function in general
What are the four steps of cellular respiration?
Glycolysis, Pyruvate oxidation, krebs cycle, and the electron transport chain
Where do the four steps of cellular respiration take place?
- Cytoplasm
- Nearing the Mitochondria
3-4. In mitochondria
What are the two parts of Photosynthesis and where are they?
- Light reaction (Thylakoid membrane)
- Calvin Cycle (Stroma)
What is transcription and where does it occur
transcription is when the DNA helps get created into RNA in the nucleus
What is translation and where does it occur
Translation is when the RNA acts as a blueprint to create proteins and it occurs in the ribosomes
An example of simple diffusion
H2O through the membrane (osmosis)
An example of facilitated diffusion
Glucose moving down a special protein transport
What is diffusion
Molecules moving from a high to low concentrated area.
How does the sodium-potassium pump work
- 3 sodium bind to pump
- Phosphorus from ATP is transferred
- shape Is changed, sodium released
- 2 potassium pumped, phosphorus freed
- Pump changes and 2 potassium come inside the cell
- cycle repeats
What is facilitated diffusion
molecules that move down protein transports
