People will have a harder time exchanging goods and services and many businesses will shut down as a result.
Answer:
- In glycolysis, glucose is split into two pyruvate and makes some ATP
- The Krebs cycle produces ATP, NADH and CO2
- NADH gives electrons to the ETC
- As electrons move down the ETC, a H+ gradient is made
- H+ pass through the ATP synthase to make ATP
Explanation:
This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).
- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.
- Kreb's cycle produces ATP, NADH and CO2.
- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).
- Electrons move down the ETC to produce a proton (H+) gradient
- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.
Answer:
Option (d).
Explanation:
Telomere may be defined as the repetitive DNA sequence present at the ends of the chromosomes. Telomeres consists of the nucleotide sequence rich in G and consists of vertebrate sequence AGGGTT.
The mutation in telomerase enzyme can cause the excessive replication of the telomeres. These leads to the excessive cellular proliferation and makes the cell immortal. This extensive growth of telomere is one of the maine reason of the cancer development.
Thus, the correct answer is option (d).
Answer:
C. 48
Explanation:
Simple thing to bear in mind; The number of neutrons is equal to the Atomic number - the Mass number. Because the Atomic number tells you the number of Protons, whilst the mass number tells you the number of both PROTONS and NEUTRONS. So 84 - 36 is 48. You have 48 neutrons
