Both pH and Heat effect catalase function therefore we will measure the function based upon changing these variables.
Answer:
The nucleus contains a cell's DNA.
Answer:
D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Explanation:
The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.
The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.
In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.

Explanation:
<u>Answer:</u>
<em>By carb loading the glucose stored as glycogen can be used to derive energy which increases a runner’s endurance. </em>Two choices that support the answer are
Mitochondria in the muscles generate energy through cellular respiration.
<em>Lungs support cellular respiration by providing the oxygen needed to produce ATP from carbohydrates.</em>
<u>Explanation:</u>
Carb loading is the process of increasing the content of carbohydrate in the diet to acquire energy for athletic activities. Excess glucose in the body is stored as glycogen in the liver as well as muscles. <em>During high endurance physical activities the glycogen in the muscles is used to derive energy. </em>
The glycogen gets converted to ATP by the process of cellular respiration. The mitochondria in the muscle cells perform the process of generating energy. The glycogen in liver is released into the blood stream when needed so as to maintain blood sugar levels. <em>But the glycogen in muscles is used for giving energy to perform physical activities. </em>
