<span>R group (or side chain) is an organic component of amino acids that is unique to each amino acid. </span> <span>Three of the amino acids have basic side chains at neutral pH: arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base and their pKa's are high enough that they tend to bind protons, (positive charge). Aspartic acid or aspartate (Asp) and glutamic acid or glutamate (Glu) are acidic amino acids because their side chains have carboxylic acid groups whose pKa's are low enough to lose protons, (negatively charged). The non-polar amino acids contain uncharged functional groups<span> at physiological pH and are incapable of participating in hydrogen bonding. </span></span>
Answer
:a. Cellular Respiration – what type of reaction? EXERGONIC .and how much energy 34 ATPs;Net gain of 32.
b. Why doesn’t sugar just explode on our countertops- sugar is a high energy-rich compound. Therefore high energy is needed to breakdown the bond-energy in it for phosphorylation to take place in glycolysis
c.<u> Photosynthesis – what type of reaction-</u>ENDOGONIC ….how much energy 18 ATPs used up and 12NADPHs
d.Where does the activation energy come from for photosynthesis SUNLIGHT
e. <u>Day to day, we use</u> ATPS <u> it is our energy coinage, we c</u>an STORE it and then cash it in.
f. What is the delta G value for breaking ATP down into ADP=−30.5 kJ/mol
Explanation:
Answer:
I believe it's B, its been a while since I last studied cells so I might be wrong
Explanation:
Hydrogen atoms are compressed
together by the enormous gravitational force
of the sun, causing them to fuse int a helium atom (which is heavier than
hydrogen), subatomic particles and enormous
release of atomic energy. The attached
picture shows the sequence of the main reaction
at the core of the sun.
This would be called an ion. Tch.
