The Nobel Prize for the discovery of TCA cycle and ATP biosynthesis was awarded to

Options

A. Hans Krebs
B. Lipman
C. Krebs and Lipman jointly
D. Vishniac and Ochoa

Explanation

To answer the question regarding who was awarded the Nobel Prize for the discovery of the TCA cycle and ATP biosynthesis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the TCA Cycle**: The TCA cycle, also known as the Tricarboxylic Acid Cycle or Krebs Cycle, is a series of chemical reactions crucial for cellular respiration and energy production.

2. **Discoverer of the TCA Cycle**: The TCA cycle was discovered by Hans Adolf Krebs in 1940. This is an important detail as it links the cycle to its discoverer.

3. **Understanding ATP Biosynthesis**: ATP (Adenosine Triphosphate) is the energy currency of the cell. The process of ATP biosynthesis involves the formation of ATP from ADP and inorganic phosphate.

4. **Discoverer of ATP Biosynthesis**: The discovery of the ATP biosynthesis process is attributed to Fritz Lipmann, who contributed significantly to understanding how ATP is formed in cells.

5. **Nobel Prize Award**: Both Hans Adolf Krebs and Fritz Lipmann were jointly awarded the Nobel Prize in Physiology or Medicine in 1953 for their discoveries related to the TCA cycle and ATP biosynthesis.

6. **Final Answer**: Therefore, the correct answer to the question is that the Nobel Prize for the discovery of the TCA cycle and ATP biosynthesis was awarded to Hans Adolf Krebs and Fritz Lipmann jointly.
