Answer: c. Transition Reaction
Explanation:
During the transition reaction, Acetyl-CoA is formed and connects the first stage of glycolysis with the Krebs Cycle (Citric Acid Cycle). In the presence of oxygen, pyruvate enters the mitochondria and is oxidized to form a compound of 2 carbon, acetate, with energy and CO2 release. During this process, the acetate binds to a coenzyme(coenzyme A (CoA)) - forming the acetyl-coenzyme A.
The 3 steps:
1. pyruvate is oxidized and forms acetate with liberation of CO2;
2. the energy released in the oxidation of pyruvate is stored in the reduction reaction of NAD+ to NADH + H+
3. The acetate molecule combines with coenzyme A to form acetyl-coenzyme A.
Answer:
Because a food chain is very limited and only follows one path while a food web consists of many food chains made into one food web
Explanation:
Answer:
The answer is C
Explanation:
Proteins that were sinthesized in the endoplasmic reticulum are able to leave this organelle inside vesicles that are formed through evagination of the reticulum membrane. These vesicles can merge with the golgi membrane, spreading its contents inside the golgi apparatus. This process can be repeated through all of Golgi's cisternaes, and when the last cisternae is reached, these vesicles can be directed towards the plasma membrane. Once the vesicles and the plasma membrane are merged, all the molecules that were contained inside the vesicle are exported from the cell into the extracellular space.
Answer
Wind may be involved in the formation of sandstone arches by facilitating erosion which wore away exposed sections of rocks and enlarges the cracks on the surface forming marrow sandstone fins.
Explanation
Sandstone arches can be formed when a large piece of sandstone flaked off as a result of high winds. In addition to that, alternative frost and thawing can result into crumbling of porous sandstone which will in the long run cut through some fins. These resulting holes enlarge to form arches with effects of weathering and rock fall caused by wind.
