photosynthesis&respi

QuestionAnswer
those that break down organic molecules for energy catabolic pathways
those that build up organic molecules to store energy for later use. anabolic pathways
All living organisms perform some kind of cellular respiration
a chemical pathway in which organic molecules are broken down to release energy in a quickly usable form ATP
Cellular respiration can be divided into two basic categories aerobic and anaerobic
uses molecular oxygen (O2) as the final electron acceptor in the reaction pathway Aerobic respiration
Anaerobic pathways do not use oxygen as they perform respiration; these include anaerobic respiration and fermentation
Aerobic Respiration Formula C6H12O6 + 6O2 + 6H2O → 6CO2 + 12H2O + energy (ATP)
Photosynthesis Formula 6CO2 + 12H2O + energy (light) → C6H12O6 + 6O2 + 6H2O
is the first stage of aerobic respiration Glycolysis
glucose Formula (C6H12O6)
Glycolysis takes place in the cytosol of cells
involves the conversion of each pyruvate into acetyl-CoA, releasing one CO2 for each pyruvate reactant The formation of acetyl CoA
oxidizes the remaining carbon atoms of each acetyl-CoA to CO2. The citric acid cycle
During each of the first three stages, the original organic carbon atoms are oxidized to CO2 as their electrons are collected into the high energy compounds NADH and FADH2
In the final stage, oxidative phosphorylation, NADH and FADH2 deliver their energy-rich electrons into the electron transport chain (ETC).
a pathway present in some prokaryotes, is remarkably similar to aerobic respiration Anaerobic respiration
Another alternative to aerobic respiration is fermentation
is the opposite of respiration photosynthesis
Plants, algae, and some kinds of bacteria are capable of performing photosynthesis
Photosynthesis takes place entirely inside The chloroplasts.
occur within the thylakoid membrane of chloroplasts light-dependent reactions
The carbon fixation reactions, also called the Calvin cycle
sometimes reduces the efficiency of photosynthesis photorespiration

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
