Cellular Respiration
Metabolism
The relationship between photosynthesis and respiration. The synthesis of ATP and ADP and inorganic phosphate, and its role as the immediate source of energy for biological processes.
- ATP is required for endothermic processes, but can be re-synthesized when coupled to exothermic processes.
- ATP is synthesized across the inner membranes of the mitochondria and chloroplasts, hence they are adapted to give the maximum surface area. AT[ase enzymes are powered by a proton gradient that provides the energy for ATP synthesis.
- NADH (NADPH is used in photosynthesis) and FADH2 are reduced co-enzymes that are used to carry electrons to a different part of the organelle.
Cellular Respiration
Respiration as the process by which energy in organic molecules is made available for other processes within and organism. The structure and role of mitochondria in respiration. The biochemistry of aerobic respiration only in sufficient detail to show that:
- Glycolysis involves the oxidation of glucose to pyruvate with a net gain of ATP and reduced NAD. Pyruvate combines with co-enzyme A to produce acetyl co enzyme A.
- Acetyle coenzyme A combines with four-C molecule to produce six-C molecule which enters Krebs production of ATP and reduced coenzyme (NAD or FAD).
- Synthesis of ATP is associated with the electron transport chain.
Learn the 4 stages of aerobic respiration
- Glycolysis (in the cytosol)
- The link reaction in the matrix: pyruvic acid reacts with coenzyme A to form Acetyl coenzyme A and release CO2
- Kreb cycle in the matrix
- Electron transport chain in the cristae.
rE: Elizabeth’s Question
I really need help on the Exploring space thing, I’ve done everything else it’s just the exploring space thing that I need help with, I looked on the blog and it said something about Galelio( not sure how you spell it) So does that mean Galelio was the first investigation thing(probe)? On google it says stuff like the telescope on Wiki Answers. Which one’s right? Is any of them right??
—————————————————————————————-
Here is my answer for the question. Elizabeth, Galileo is the name of a probe which was launched in 1995 to observe the space. The difference between space probe like Galileo and telescope is that space probe stays in space but telescope is placed in Earth. As the other article says, the space probe provides us with vivid picture since the space is vacuum. My question in the book is asking you “where they went and what they found out”.
Galileo travels around space and it has also entered Jupiter’ atmosphere.
So it went to Jupiter and Venus. Throughout its long journey, Galileo has sent data(information) about solar system back to Earth.
But Galileo plunged into Jupiter’s crushing atmosphere on Sept. 21, 2003. The spacecraft was deliberately destroyed to protect one of its own discoveries – a possible ocean beneath the icy crust of the moon Europa.
Galileo changed the way we look at our solar system. The spacecraft was the first to fly past an asteroid and the first to discover a moon of an asteroid. It provided the only direct observations of a comet colliding with a planet. Galileo was the first to measure Jupiter’s atmosphere.
Don’t really know if it was the first space probe ever.
