Answer: protons
Explanation: atoms of each element contain a characteristic number of protons
Answer:
Active transport of calcium into the sarcoplasmic reticulum.
Explanation:
- The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca2+)
- In response to an action potential traveling along the t tubule, voltage-sensitive proteins change shape, opening calcium channels in the adjacent terminal cisterns of the sarcoplasmic reticulum.
Answer: (A) a membrane‑bound organelle with stacks of thylakoid discs called grana.
(E) the main site of photosynthesis in a plant cell.
Explanation:
The plant chloroplast is a large organelle, it is bounded by a double membrane like structure that is chloroplast envelop.
The chloroplast consists of chlorophyll pigment which traps the light energy from sun and converts it into chemical energy in the form of ATP. Thus the chloroplast is the main site for photosynthesis. Including the inner and outer membrane structure it also posses the third internal membrane structure which is called as the thylakoid membrane. The thylakoid membrane forms the network of flat discs which are called as thylakoids, the thylakoids are arranged in stacks which are called as grana.
The thylakoid membrane is the center point for the synthesis of ATP through a chemiosmotic process.
Answer:
The correct answer is - 1.
Explanation:
Given:
The question says to take a number add 2 multiply 2 minus two and divided by 2 and minus the number thought so the numerical representation would be
=> (if x = 1)
Solution:
According to the ques
2+1 = 3
3*2= 6
6-2= 4
4/2 = 2
2- 1 = 1
